When i go to work all my co workers always talk about other women even though they are all married. they always laugh at me when i say i don't care about other women because i love my wife
Im sorry to hear that! Are they trying to shame or embarrass you about something. 
they just say that men can't be faithful, that all of us cheat and stuff like that. It's not true! I mean i really can't imagine cheating on my wife
You seem like a trusting guy. there are not too many of those these days
