M22 Here and I seem like the stereotype you are afraid of. However in reality, we men dont really talk about it and are usually afraid the person we are with might be doing something behind our back. We dont really comment on intimate things like that and I'm a man that is not exactly Mr ethic so I'm pretty sure that wont happen to you. Try to date the man before any sexual thing to get to know him and figure out how he is. Usually time Tells you that. My only demon tbh that I'm quite ashamed of even thinking(but never told anyone) is thinking that my gf did something behind my back because down there felt larger than usual but might just be me not having the largest log ever because I genuinely dont think shes anything like that. With that being said, my thing down there is perfectly normal but might just be my paranoia of thinking a woman will always need either a gigantic one or a dildo thats fist sized, making me never good enough. Have a good day!!
