I’m 18 and my boyfriend has just turned 21, we’ve been together almost 8 months and we’ve never argued or had any real rough patches. But since about October/November it’s become really rare that we have sex.

It was about a month without it so I talked to him about it, and he said he’s not really sure why he has no sex drive and that it’s probably from stress. He gets stress problems from work and just general irritability. After a month of nothing we had sex a few times (still only once every few weeks or something) so I thought it was going back to normal but now it’s been a month and a half with no sex, no foreplay, making out or anything.I brought it up again and he said pretty much the same as before, but he seems surprised that it’s bothering me so much, I’ve tried to get things going but it never happens and I really don’t know what to do anymore.

At the start of our relationship we’d have sex every night that we spent together so maybe 3-4 times a week and I just don’t understand why it’s changed so suddenly. People have suggested to me that he could be cheating but I know that’s unlikely, he’s very honest and has been treated badly before and is loyal, he’s not the kind of guy to flirt with other girls or anything like that.
