This is a true story.
A few months after my first gay experience as a straight man, I booked a session with a masseur at a massage parlour. I had no idea what he looked like, just his name and a few words about him.
I waited a while for him at the parlour, as apparently he'd not realised about the booking. A short man in his forties with a neat little beard and tattoos on his arms came up to me and apologised. I immediately realised two things. First, Tom was obviously gay. Second, although not on paper my type, I was quite attracted to him. I liked the fact that I was old enough to be his dad. Also -- well, you often can't put it into words. Something about his smile, and the gentle way he spoke.
We went down to the massage room in the basement. I always liked the idea of being massaged in the nude but never had the courage to ask for it. Same this time -- I had white underwear on, although a fully dressed Tom pulled the undies down quite a way to give me a good doing over on my gluteus maximus, which I loved.
While he was doing my feet, I discreetly (I thought) wanked myself, I was so turned on. He made no comment but on another occasion when asked said yes, he'd noticed.
When we were finishing I gave him a good tip, the first ever after a massage (it's not normal where I live). He profusely thanked me and mentioned that he was leaving the practice and would instead offer massages at his own apartment. I took his details, of course.
