I'm so in the mood & he is so not.

This past week has been HARD. I've been so incredibly stressed from school, which has sadly started some unwanted fights with my bf of 3 years. I usually only see my bf Thursdays-Sundays because of college, but this week I saw him on a Tuesday as well since I was down in the area. That day we ended up doing it. But since seeing him since Thursday after a few more fights, he's just not in the mood. He'll tease me, play with me, & even took pics of me...but he's just not in the mood this week. It makes me worry, but he always tells me to not worry about anything...he'll be in the mood soon. I think my mood is just up this week for some reason, but is this normal for guys to not be in the mood for a week of two? I know my relationship isn't all about sex, but I've just been craving it.
