Two year relationship. This is sort of funny but here it goes..

Due to some scheduling conflicts, work ended up being really slow this morning, so my boss let me take the rest of the day off. I figured cool, now I can surprise my boyfriend with breakfast since I figured he was probably still sleeping.

I got home and immediately went to our bedroom to wake him up and that's when I caught him masturbating to a picture of me. The look on his face was priceless. HAHAHA! Obviously I "helped" him out but the problem is...

My boyfriend always lies and says he never masturbates. Why would he try and hide that from me? It's really no big deal, especially if he's using my pictures. 

Sometimes, he's not up for sex and I wonder if it's because he jacked off earlier in the day. Is this something I should talk to him about or should I just let this go?
