My boyfriend and I have been together for almost half a year now. Everytime we have sex I always have an orgasm which is awesome, but there are many times that he does not finish. My boyfriend was a virgin until me, but I had already had sex with 3 people prior to him and I have more experience. His penis isn't small but it's not big either, and I'm larger than him. What I'm wondering is if it is possible I am too loose because I've had sex with 4 people now or if he's not big enough or if I'm just not doing it good enough or if it's because I am larger than him. The only time I orgasm or he does is when I am on top.
