Okay my boyfriend and i have been together almost a year now and when we have sex i seem to enjoy it more than he does he seems to not get as much pleasure as he did when we first began having sex and it takes him a long while to cum he has told me it doesnt feel the same yet to me it feels different every time he has lack of pleasure it has been like this for at least a month i fear its my fault any help or suggestions i have medical issues with my stomach could that cause it?
