A straight friend of mine once asked me when I first decided I was gay. I told him it was March 12, 1972, about 6:00 o'clock in the morning. I was in the bathroom shaving and watching myself in the mirror. I began to evaluate my life and where it was heading. Then I thought, "You know, I think that from this moment on, starting today, right now, I'm going to find men instead of women sexually attractive and compatible. Yeah, that sounds right. That's my new plan! Damn, glad I got that out of the way!" Then I looked at my friend in way that made him know I thought he'd asked a stupid question.
It's not a decision, it's a discovery. It's not a choice, it's more like left to chance. As others have said, science doesn't have a fully developed and definitive explanation of the cause of homosexuality, nor of heterosexuality for that matter, other than it's the norm of the species. But just as there are dark-haired Swedes and blond Italians, individuals can sometimes differ from the norms.
It's also not uniform, it's a scale. Some men are completely straight (at 0 on the scale) and others are exclusively gay (or as I call it, a perfect 10). The OP is bisexual, which does give him a range of choices. But I'm not bi, and certainly not straight, so my choices are more limited.
The closet I've ever been to female genitalia was at birth, and I've never looked back. I like my women like I like my coffee. I don't like coffee. And if someone would ask me what I'd like in a woman, I'd say I like mine on the taller side, with broader shoulders and a bigger d**k.
But that's just me. YMMV.
Yes. You've made your point previously.
You view sexual orientation as biological and lifestyle as a choice.
But others disagree. "Sexual Orientation" has dimensions of reality beyond biology:
The dimensions consist of sexual attraction, sexual behavior, sexual fantasies, emotional preference, social preference, lifestyle preference, and self-identification,
