This is a vagina.
You see the part labeled “vagina”
that’s the part that every clueless dude (me included, I’m not better than you) THINKS you’re supposed to lick. That does almost nothing for the girl. It feels nice in the sense that someone putting their hand on your crotch feels nice; sure, you may get hard, you’re probably not gonna cum.
See the part labeled clitoris? THAT’S WHERE YOU LIVE NOW.
suck it, lick it, flick it with your tongue, make little designs and symbols, do the alphabet, pretend you’re a sewing machine, do circles, write your initials, whatever.
if you’re focusing on the clit your odds of making her cum go up like 10000%
you can finger her/rub her clit/etc while you’re giving your head, but that’s all based on personal style and her personal preference.
but rule of thumb, you live at the clit if you’re giving her head.
If you’re licking her vagina you’re not doing shit, she’ll probably look at you with the “Oh, Honey” face. You tried, and (like most sad women) usually just give up hope right then and there.
Theoretically you can just do that intentionally to get out of giving head, but then not only are you unproductive but you’re a fucking asshole, but whatever.
TL;DR: do any and everything to the clit. you’ll know she’s liking it cuz she won’t lay their silently disappointed like a board.
BECOME THE CLIT COMMANDER.
