Me and my....friend with benefits who I practically live with are going through a seemingly endless drought. It's probably been about 5 or 6 weeks. He seems to want it when he wants it, which is few and far between. I'm thinking of asking him whether he took a vow of chastity as his new Year's resolution without telling me, or is this slightly too harsh? I'm in my late 20's, he's 10 years older, and over time the 'action' has become less and less...starting to feel really resentful and angry. How do I broach the subject?
