Yes, this!! Think of it like trying to get a squirrel to eat from your hand. No sudden startling moves lol.. and be aware that the most he might be up for is letting you stroke his tool or something. Saying “mmm, feels good” if what feels like his tool (or his muscles) touch your again - that’s a good start. Sometimes I’ll also ask what kind of workout routine he follows - “you obviously know what you’re doing, and I thought maybe you could give me a useful tip or two..” Some straight guys like being admired and even touched as long as you don’t “threaten” their straight identity. I had a regular masseur like that before I moved. Met him through craigslist before they closed up the fun parts of their site, so the starting point was a bit different, but the same techniques of communication still apply
