You might like to approach this from his point of view. Straight men do have sex with men, either as a dare, because of drink, or due to some underlying curiosity. None if it makes them gay or bisexual unless they actually are.
Some will be, some will deny it to their death, but play when the opportunity arises. You could say to your friend that what you both did was cool with you, but that you value his friendship above any intimacy you shared. Say it was a nice experience, but it ends there unless he chooses otherwise.
Then never mention it again and try if you can to divert your attention away from the wishful thinking in your mind. Hard for you I know because your focus on this guy is very real for you, but feelings that are not mutual or equal have no mileage for anything satisfying in the future. Treat it for what it was, a likely one off man on man intimacy that probably in reality means nothing more than that.
Hopefully you'll soon find a guy who wants to share the intimacy you need and who might trigger real sexual chemistry between you. It's only a matter of time!
Gay guys date other gay guys, not bisexuals.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
