It's all I do.
I was completely inexperienced until I was 32. Lots of reason: the closet, self-doubt, moral compunctions, body image, past rejections, whatever.
Then, an 18-yr-old friend led me on for months when I was 32. I finally said something, he ghosted. A couple months later, the opportunity arose to blow a 25-yr-old guy, I said "fuck it" and did. I'm 37 now, I only blow under 26ish.
I like the idea of the tables being turned, the feeling of being used by younger men. I like using my body to teach skinny waifs that they can be dominant and top, that their pleasure matters.
It's difficult to find young men who are into older. There's immense, but recent, social programming that any interaction beyond a year's age difference is freakish. Age discrimination isn't viewed as problematic by woke gays (forever reading oblivious grindr profiles like "if you have race preferences, don't hit me up. No one over 25.")
Sometimes you just have to lay it down straight for a younger guy: "we're talking about a blowjob, not marriage." It's worked a few times.
One of my best was a guy who was in the area on vacation. He was very enthusiastic because he was very new to sex, but his only partner had been a teacher who was intent on squarepegging him into bottoming, which he hated. I was happy to let him take out his intergenerational frustration on my throat. He told me he how grateful he was for letting him be himself and take control. He smothered me with clumsy, hard kisses that honestly hurt my lips, but I loved that he was getting to do what he wanted, and to feel the way he wanted to feel in his position in the situation.
I just love giving them what they want.
