Look deep in to your heart about how you feel for this guy, if you truly love him then you will find a way to move forward. But always protect your self he might of done more that he's not telling use condoms tell to get tests done. What ever you need to do to protect you and your heart.
I would find out how he truly feels about you and your relationship, and that this curiosity won't happen again in the future. Good luck. The rest you have to way up.
But protect yourself.
End it... the butt thing is gross. Also you don't wanna catch something if he might be sleeping around.
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.
