Fingers In Your Mouth During Sex: The Reasons And The How-To

Getting fingers pushed into your mouth mid-sex can land as scorching, unremarkable, or straight-up strange — it's all about the moment. This piece breaks down 8 reasons guys do this, how to get your hands ready, and 9 ways to turn mouth-fingering into something extra kinky.

8 Reasons Why Guys Put Their Fingers in Your Mouth During Sex

Why does anyone do anything once the clothes come off?

Honest answer:

It's all over the map!

Still, here's a rundown of the common motivations behind a guy slipping a finger into your mouth mid-romp:

1. Mimicking a blow job – Working his fingers in and out of your mouth in a rhythm close to thrusting can echo the sensation of oral sex and edge toward a double-penetration feel. Pair it with a toy like a butt plug elsewhere and the fingers-in-mouth move cranks the intensity up further.

2. Asserting control – Fingers pushed into a mouth during sex can read as a dominance move (tips on taking charge in bed). The message is basically "Watch what I can do to you." Pair it with an open mouth gag and the invitation to "fill this space" becomes obvious. You can also issue direct instructions about sucking during the act.

Fingers-in-mouth can double as embarrassing or humiliating too, which works great if erotic humiliation is already on your shared menu.

There's also room to lightly steer someone's head or face using fingers hooked in their mouth.

3. Copying porn – Some men do this simply because they watched it on screen and assumed it's expected, or figured a partner would automatically be into it.

Not great, honestly...

Talking about turn-ons and no-gos ahead of time usually beats guessing. Grab some pointers for talking about sex.

4. It's just their thing – Some folks are genuinely wired to enjoy fingers in mouths, either receiving or giving (browse the full kink and fetish list). Maybe it's the warm wetness, maybe it's the taboo factor, or maybe there's no deeper "why" at all.

5. Some men just find it sensual – For plenty of people, maximizing skin contact or filling every available opening is a massive turn-on. Others simply love watching a mouth work on a body part, finger or thumb included.

6. Angling for reciprocity – Sometimes what we do to a partner is really a nudge toward what we want done to us. As mentioned, saying it out loud tends to work better than hinting.

7. Sharing a taste – Fingers can carry a scent or fluid from one place to another after they've been inside you or covered in cum (how to swallow cum comfortably).

8. Because it feels amazing – A warm mouth with a soft, capable tongue is just... a good time! So there's that.

Almost anything nestled inside that mouth is going to feel good, and fingers happen to be one of the few body parts that actually fit — though some people extend the love to sucking on toes too.

4 Preparation Tips Before Fingering Your Partner's Mouth

One of the easiest things to forget about mouth-fingering:

Getting ready first!

Prep work is what makes the whole thing more enjoyable for your partner.

1. Clean hands – Starting with washed hands matters for hygiene, unless you're deliberately introducing a specific scent or flavor.

2. Softened skin – If your hands and fingers are rough or calloused, try exfoliating or filing them down, then finish with a moisturizer to keep things smooth.

3. Cut and file nails – Trimmed, filed nails cut way down on the odds of accidentally poking, scratching, or nicking someone — especially important since a cut in the mouth can get infected fast.

If you'd rather keep your length, try gloves instead. Stuffing cotton balls into the fingertips helps prevent stray pokes.

If your nails are painted, allow extra drying time and finish with a fast-drying topcoat so your manicure survives.

4. Talk it through with your partner – Prepped fingers don't mean a prepped mindset. Cover what's welcome and what's off-limits regarding timing and technique before diving in. Skip this step and you risk a bite or an unwanted gag reflex — not fun for anyone.

How to Make Fingering Their Mouth Hot & Sexy – 9 Tips

Like most things in the bedroom, easing in beats...

Shoving your fingers into an unprepared mouth out of nowhere. Below are ways to build up gradually before ramping into rougher territory.

1. Trace their lips first – Start by running a finger or two lightly along your partner's lips.

• Hold them still against the lips as an invitation to kiss.

• Rest two fingers on their mouth and part them slightly so your partner's tongue can slip between.

• Try tugging the lower lip gently downward with your fingertip.

• Once your partner opens up on their own, slide a finger in.

• You can also instruct them to open, or press lightly against their lips as a cue, before moving into actual finger-sucking.

2. Start with one finger – Ease in with a single finger first so you both get comfortable before adding more. If one finger already isn't landing, more probably won't fix it — better to pivot to something else.

3. Move to multiple fingers – Once a single finger is working well, add another. Keep them pressed together, or spread them apart to stretch your partner's cheeks.

4. Swap in your thumb – A thumb instead of a finger is still a digit, but it delivers a noticeably different feel.

You can insert it either way up. Using just the thumb frees your remaining fingers to rest on or stroke your partner's face. Being thicker and shorter, thumbs also tend to be easier to suck on than several fingers at once — handy as a warm-up for oral sex technique.

5. Turn up the intensity – Getting more aggressive with mouth-fingering might look like:

• Pressing your fingers further back toward the throat
• Hooking a cheek from the inside
• Applying pressure against the teeth
• Prying the mouth open wider for a toy like a dildo or your penis
• Using your fingers as a handle to reposition your partner

6. Have them taste themselves – As mentioned, fingers are a great vehicle for delivering a specific flavor to your partner — commonly done right after fingering them or giving a hand job.

Or if cum ends up on your fingers, let your partner lick and suck it clean.

7. Play with different positions – Try mouth-fingering face-to-face, or from behind — during doggy style or anal sex, for instance. Each angle brings its own sensation and options. From behind, for example, you're well positioned to pull hair while your fingers stay in their mouth.

Go deeper: Hair pulling during sex — a how-to.

This angle also sets you up nicely to cover their mouth with your hand, especially useful if they moan loudly (or cry out, if you're leaning into rougher sex).

8. Use it as a segue – Mouth-fingering can serve as a warm-up act before a toy or penis enters the picture.

It can also lead naturally into kissing once you withdraw your fingers. You could even kiss "around" your fingers as you slide them out.

9. Check in afterward – As always, comparing notes on what landed and what didn't keeps things fun going forward! Ask through some dirty talk in the moment — a quick "You like that, baby?" — or bring it up more deliberately once you're basking in the afterglow.

And with that, you're ready to experiment with something new in bed.
