Black men are stereotyped as being hyper-sexual and having huge cocks. It tickles a "kinky-forbidden-sex" angle for white women - and gay/bi white men - to fantasize about. I think the hyper-sexual stereotype is dubious. Libido and sexual skill are probably about the same for all races. But larger size (on average) of men with sub-Saharan African heritage is supported by medical statistics.
I wanted to live out some of my dom/sub fantasies. We met on CraigsList and got a motel room (I'm married and a closet Bi). He definitely had the dominance role down cold. Around 40, in good physical condition, and a cock that was 7 or 8 inches. He taught me how to deep-throat him in the context of dominance and submission...on my back with my head hanging over the side of the bed; him standing behind my head and thrusting. Slow and patient penetration at first, as I gagged several times. Fucking my throat more forcefully when I was able to take it.
Totally hot sex! Definite sore throat.
If he had come on more aggressively with face-fucking, I probably would not have enjoyed it.
Armpits have a sexual smell. It's why they have hair there... to better send out their scent. I like erotic pictures of women whose armpit hair is natural but not "heavy". My wife was natural, with wispy light-colored hair, when we met back in the hippy era. But she eventually shaved it, a long time ago, and she hasn't let it grow back since.
I'm a closeted bisexual. The hetero side of my sexuality is taken care of exclusively with my wife (who isn't into anything remotely adventurous in bed). The gay side consists of much more exciting semi-anonymous encounters with men... mostly closeted bi guys like myself.
I don't get with men very often, but sometimes I have to scratch the itch. I DEFINITELY love a nice cock in my mouth... and getting reciprocation.
A few years ago there was a weekly gay orgy in my city. Usually 30 naked guys, with diverse ages and ethnicities, doing everything (except BDSM), with multiple partners. It was in the finished basement of a townhouse in a nice urban neighborhood; lunchtime on Wednesdays, lasting 2 hours. A $10 "contribution" while coming in the back of the house. I only went five times, and then the homeowner discontinued it. I usually went around sucking multiple appealing cocks, and being sucked. Usually just a few minutes each, with no orgasm. But sometimes with the same guy for an extended time, orgasming while others watched. Didn't fuck, but I enjoyed watching close-up when guys did.
As for how to give a blowjob... try googling "how to give a blowjob". And watch some M/M cock-sucking videos (because men are usually better at it than women). And don't be worried if you can't take a cock into your throat. It's a skill that takes practice (and many cock-suckers choose not to do it at all).
As for how to hook up with a man, aren't there phone apps for that?
I get turned on by dom/sub role-play, with me being the submissive one. Being called a faggot cocksucker while I have a stiff penis fucking my mouth is a definite turn-on.
I get off on being bare-ass spanked by a dominant man or woman too. I guess that qualifies as "mean".
"Firsts" are always memorable... first masturbation orgasm; first handjob/blowjob/fuck. I don't remember my first "edging" masturbation session, but edging for an hour has always produced stunning orgasms ever since.
I'm into Dom/Sub role-play, as the Sub. Mild humiliation, such as being called a faggot cocksucker, is a hot element of sex with a demanding Dom. I fantasize about more intense humiliation, but haven't taken it beyond the JO-fantasy stage.
