why do people use being asexual for not being in any relationship? being asexual or bisexual or homosexual or heterosexual is not an excuse if you just aren't interested in someone.

yeah, the attraction to the correct gender may be a contributing factor but is it really necessary to tell someone 'no, not interested, I'm gay/straight/bi/a'?

grow a spine and just say 'flattered, thanks but not interested'.
