Myself and my girlfriend really don't have anything to compare to having been both virgins to start off with, so we're just happy to have the opportunity to improve when we can, and I'm not worrying too much about her comparing technique that say another more experienced guy would apply. It's just a matter of practice, practice, practice.
Still I have to work on my stamina abit...otherwise I'm sure it would be as awesome for her as it is for myself, I try. I've made my apologies before if it seems to have fallen short for her, but she hasn't left me yet and she never said "Thats
it??" I just say I can't help but be overcome by her.
