Is He Bad at Sex?

Sydney writes, I am in a heterosexual relationship. We haven't had sex or any kind of sexual relations in over three months now. He has a recent health condition for which he takes meds that affects his sex drive and desire. It's not that he's quote, bad at sex. We just don't have it at all because he doesn't really have that sexual desire. How do I deal with no sex when it's something I've been needing and missing?
