A few days ago, I was hanging out with this guy I work with. I've known him for about a year, but we never did anything outside of work until the other night. He's 19 and I know he's a virgin. He's a little stocky and not bad looking though. Anyway, we were at my apartment and I kept wondering if he'd wanna mess around with me. We drank a few beers and I suggested we watch a porno. A straight porno, cuz I didn't wanna freak him out. Eventually I told him the porno was making me horny and asked him if it was ok if I took my dick out and jerked. He said it was ok (he seemed a little weirded out by it though). After awhile, I suggested he just take his out too. We were both sitting on the couch together, but on opposite sides. He hesitated but soon he unzipped and started stroking it. Watching him jerk off made me cum about two minutes later. He kept whacking it and came a few minutes after that. Afterwards, I gave him a towel to clean up. He smoked a cigarette and then left soon after.
My question: Does this experience mean that he'd be down to try something gay in the future? I'm afraid to come on to him cuz I work with him and if he said no, it could make things weird. But we sat on the couch and jerked off near each other, that's something right? He hasn't spoken about it to me at work or acted differently at all since then. Any advice?
