How I found out what fundamentally turns me on?

Even though I knew I was gay when I was 8 or 9, and that I never was interested in women, I did not find what made me attracted to men… Was it the body shape? One day, at the country swimming hole, I saw a very athletic black girl in a yellow one piece suit. This is one of the very few times a girl gave me a hardon… It could be, because my fapping material were the usual Sears-like catalogues, in the boys swimming wear sections (but sometime I found men hot). I mean, I was only 13-14… I had sex with boys my age, and it wouldn’t be until I’d be much older that I’d have sex with a man much older than I (I was 30 and he was 50 and asian)… And what made me attracted to asians the most? It wasn’t the beautiful long, straight, black hair, because I’ve had boyfriends (and crushes) who shaved their heads… It wasn’t the eyes either because the guy I’m with on-and-off for 30+ years, although asian, doesn’t have the characteristic eyes… Well, a white guy gave me the answer: it’s the shape of the face… He had an asian face, but not the eyes and curly red hair. Despite that, instant hardon… So, that’s one thing settled… Then I noticed blacks had similarly-shaped faces. Cheekbones = hardon. And another thing I love with blacks is they often have a long, hard look at my spandex bulge… But for men, what do I look in a man so to get turned on? Well, I found out one day at the sauna. It was a new sauna, which had a sensibly big whirlpool (whenever I go to a sauna, I always ask if the whirlpool works), so after I get my shower, I head for the whirlpool, when I notice someone a big arse and boobs. "Oh, this is strange. They let in women now?". So, since I’m totally ininterestd, I keep going into the whirlpool, and I sit down where I can survey everyone taking a shower. I’m alone in the whirlpool (which could hold 10 people easily). At this moment, the girl turns around, and out whips one of the largest dicks I have ever seen! Instant hardon! Oh my! And from what is otherwise a perfectly shaped woman… I was attracted to a girl since I’ve noticed she has a dick! Well, now that’s interesting. She finishes showering, and heads to the whirlpool. She heads straight to me. — Hello… — Hi, I answer, very obviously staring at her semi hard dick right at the surface, floating in the water… — Would you mind massaging my neck? — Of course not… She then sits in front of me, where she cannot no notice my raging hardon. I start massaging her neck, while we make casual conversation. She’s from Venezuela, and she is a well in demand escort. I have no trouble believing that… She tops and she bottoms, she says. I start kissing her neck but she says "naaah, I don’t feel for sex tonight"… — Oh, sorry. I keep gently massaging her neck, always with the raging hardon… Meanwhile, other men get into the whirlpool, and are astounded to see a woman getting massaged in there… It lasts a good 20 minutes when she calls it a day, thanks me, and starts to get up. Everyone jumped when they saw her hardon slowly emerge from the water… As she went out, I had a long hard look and she really has a woman’s body. From the rear, you’d never know! And now I know that what interests me is the dick. Big or small, a dick is what turns me on. So, what turns you on in a man?
