I'm pretty sure my friend has talked about watching sex tutorial videos before.. I imagine different things feel good for different women, which probably doesn't help much. Don't use porn as a guide though!!! If you aren't sure there is no harm in asking. It won't make you look dumb I swear. When my boyfriend and I try new things I always ask how it feels, what could be better etc.
Yeah porn is only for jollies and not a teacher, but last time I made the move/asked to go down I got "that's disgusting" and sexytimes were cancelled. Bluest of balls, man. Both sides just need to know we don't know how to do this shit out of the box, especially when previous people said "lolno" to us.
It doesn't help that there's a double standard that I saw repeated throughout later high school and by other adults where blowjobs were "AWESOME MAN :thumbsup:" and going down on a woman was seen as "EW THATS GROSS"
