My boyfriend is totally up for sex recently where my sex drive has completely gone down hill:/ but he's constantly on my case and won't stop hassling me so in the end I just go with the flow sleep with him and don't enjoy it, it's not because I don't love him or gone off him because I love him huge amounts and he is very attractive but just the odd time which is once in a blue moon I have  sex and that's when I enjoy it I don't know what to do I don't want him to wonder off somewhere else and sleep with other girls because I'm not giving it to him I have told him over and over again I haven't gone off him in the slightest !
