Me and my girlfriend were both virgins and just had a go at intercourse for the first time. Unfortunately, her vagina is really tight and is pulling the foreskin on my penis back causing pain for me and also for her. I've fingered her a few times to help loosen it up, and wore a condom to help with the lubrication, but it's just really painful. Is there something wrong with my penis, or just too much wanking?
