i dont know of that many women that can have an orgasm from their g-spot. most guys can't even find it. my ex did on me and it wasn't pleasant lol. Took me about 2-3 years of having sex before I found out what an orgasm even was! Now, I don't switch it up because I know how to get it done and that's the only way its worked for me. Its different for every female though. I would suggest masturbation to determine what you like. Once you do it for yourself, you'll be better equipped to show/tell him how to do it too.
