relationship w a man but craving women

so i’m bisexual. my whole life i’ve only been w men, dated/had sex w men. i like women a little more than men but women are just harder to talk to. i can have sex w a man but i don’t really finish. but when i get off to women i finish in like 3 minutes. so i’ve been curious about what it would be like to be w a women. maybe it’s just the ppl i’m having sex w. has anyone else had the same problem?
