Is my sexual orientation gay, bi or straight?

When I was young (before my preteens) I remember watching films and TV shows with make out/sex scenes between a man and woman. The shows always cover the breasts, private parts etc. and I do not like watching porn (but soft erotica). I've been masturbating since then (but not often) and had my first orgasm. But I am 23 man and still a virgin, not much interest in dating, but have sexual fantasies about a man and woman but I'm not there; the reason I don't fantasize myself having sex is because I never saw myself as handsome or good-looking or even muscular ( I'm like a male version of a plain Jane). I do like to look at male muscles and body built, only to be jealous of physical masculinity (I'm rather slim and slightly hairy (Mediterranean hairy that is) but I also find female beauty and feminine long hair to be attractive and admirable.
