row about who asks for sex

Me and my fiancé had a row about me never asking him for sex, in ways I can see were he's coming from but think does it really matter who asks for it as long as it happens, what are your views? I also have only had a orgasm a few times but he has an orgasm all the time and just stops wen he is finished which drives me mad has anyone had this problem before and is there anything I can use that might increase my chances of an orgasm so it can happen before he gets off
