I love it when a lady straddles my face so her vulva is on my mouth, so she has more control as I kiss and suck her clit. If she has an orgasm in that position, either before or after coitus, it really makes me feel loved! Her being on top, in the control position, during cunnilingus really turns me on, and makes me feel like she needs and wants me. To me it's just about the ultimate form of affection a woman can show me. Unfortunately it seems some women are shy about this, but I've had a couple of girlfriends who either especially liked cumming while straddling my face or at least humored me. Straddling my thigh when we kiss is very sexy too, and of course straddling my loins is very inviting, but if you really love me, show me by often straddling my face until you have a big orgasm!
All of those are nice. I think when a girl straddles you, especially your face, it shows a lot of confidence. It seems like women are more self conscious about what's in between their legs than men are, and are really hesitant to do that. I think it's hot!
I'm pretty sure most guys like it. Even if you're not wearing the lingerie. When my boyfriend and I are making out he'll pull me on top of him so I'm straddling him. That isn't something you would expect from a guy like him...
All 3. My boyfriend recently asked me to straddle his face so he could lick me "til he couldn't breathe". He's been incarcerated for 4 months and he's got 4 to go; by the time he comes home there's no way I'll last "until he can't breathe"!!!
