Sexual identity crisis aside, Dean's man enough to admit he's in love with Castiel. Has been for years. Which would be fine, really, if he could get past the whole unrequited, unworthy business, because maybe then he could move on with his life, get back to having sex on a semi-regular basis. Aaron's the first person to pique his interest in far, far too long.
Aka the one where Dean's pining for an angel, starting to accept that he maybe wants to fuck men, and he's got Aaron Bass' phone number burning a hole in his wallet.
