it varies, some girls can others cant..also depends just as much on the guy, some guys can do the trick, others cant
Yep, some girls can, some can't. I can't. I think for a lot of women it's related to gspot stimulation.
yes you can! I was 18 before I ever did, I think you have to really know what you like. For me personally, and for many others I know, being on top is the only position I can be in to have an orgasm during sex. I think it's because the clit is being stimulated in this position. You should try!
Its not unheard of for a girl not to be able to cum from just penetration. The clitoris is, after all, the female sex organ.
