I think he's crying because he's scared to know that he has changed. It's hard for straight men to accept the fact that they will fall in love with a guy. He's also scared that maybe his friend doesn't like him the same way. Now that they will have sex with his guy version his scared of the outcome. Maybe he's thinking that maybe his friend will regret his action and left him.
This is all my opinion.
TALANDEEE IRITAH HAHAHAHA CHAR
