Legit possible reasons.
1) He's gay. (already thought that anyway)
2) His dick's inverted. (def possibility considering he's Asian)
3) He can't keep a girl for any sustained amount of time because his overly sensitive, clingy nature scares and annoys the **** out of them. (my actual reason he'll never get married)
4) He's gay. (too many indicators point in this direction, not that there's anything wrong with it)
5) His only sexual experience lasted five seconds and ended with him prematurely finishing into his partner, knocking her up, and fathering a child, someone that he has never been allowed to see and will never see because of his creepy interests in celebrity relationships and anything lavendar, thus scarring him both emotionally and even physically since that same partner, furious after his terrible performance, scarred him just seconds after by cutting his tiny dick off, thus rendering him completely and utterly incapable of ever having sex ever again.
