Me and my boyfriend have just started having sex and theres really no problem with me but i tell him we need to use a condom but whenever hes hard and he puts it on so that we can have sex, he gets soft again. Is there a problem with him or is it the condom ? its happened all times so we just started having sex without a condom.. and he pulls out but that worries me..plz i need advice on this i dont want to end up pregnant because we cant use a condom!
