My boyfriend does not want to have sex anymore
I have been with my boyfriend for almost two years. We have lived together for a year as well. I am 20, he is 32. When we first got together we weren't serious, just lovers. And we continued to make love multiple times a day for the past year and a half or so of our relationship. Things are mostly fine with us, other than this. Lately, he doesn't even touch me sexually. He's constantly telling me we will have sex tonight after work. Then bedtime rolls around and he tells me he's too tired, but he loves me. He is very intimate with me, always kissing and holding my hand. He even bought me a really sweet picture frame for my desk at work yesterday, so I know that he is still interested in me in at least some way. It has been about a month since we have slept together. He isn't on any medication. His job is just as stressful as it has been the entire length of our relationship (he has worked at the same awful place). I just need help. I have tried seducing him, and sometimes he will mess around with me, but usually only until I finish. He doesn't. Other times, he won't engage at all, rather just go to sleep or get on his computer.
