As long as you have a functional penis those urges aren’t going away.
I try to keep myself out of situations that are too compromising.
I love my wife, but if I’m out by myself and I see something I like I’m going to look. I’m not blind nor am I dead either.
Penis discipline gets better as you get older, but you still will be tempted and occasionally tested too.
Most fellas are only faithful as their options though, that’s not to say that all men cheat but put them in the right situation with the right woman and an understanding of discretion 70-80 percent or more of fellas are going to play.
