Also, if you're using condoms during sex, have you ruled out a latex allergy?
Yup. That was actually the first thing I thought because the first time we had sex we did use condoms and my mother has an allergy. But since then we haven't been using them and have still had problems. :(
Also the We-vibe looks really interesting it's actually one I've thought about purchasing before, so thanks for the tip. I've never tried a G-spot one before ^_^
