I've had many more experience with women than I have with men, but that said, the best man on man sex I ever had was with a masculine 64 year old I met online and met with. I had never been that hot over a guy, but I couldn't seem to stop sucking his fat, rock hard, dad-dick. I have never received anal and didn't think I would want to, but I almost asked him if he would take my ass cherry, but I chickened out. But had he wanted it, I would have given it up to him in a heartbeat.
