My boyfriend and I have been together for almost a year now. I noticed we haven't had sex in 5 months. Im not the person who needs it all the time. I have been paying attention.I haven't noticed any signs of cheating. Im with him majority of the time and he calls me every night. He does not go out at all. It is nice that I don't have to worry about him not wanting sex all the time but thenat the same time I'm curious. He knows its bothering me but he hasn't said much. I feel like maybe something happened last timeI don't know. I don't want to acuse him of cheating when I don't really no.It just wouldn't make sense if he was. Im involved with his family and stuff.I go with him when he does actually go out with a friend. Could he be depressed about something?
