What do you think of a man who would send a txt pic of his to strange women?

I live with my babys father, our relationship is basically dead. but I found this pic he had taken of his willie on our Tmobile web album by accident. so I thought maybe he had a girlfriend that he didn't want to tell me about. So I asked him about it because I thought if I'm stuck in the house with his baby while he's going out with someone, its not really fair unless Im allowed to go out sometimes too. Anyway I was kind of disgusted by the explaination he gave me. He said that one of his female pengers who was very drunk (he's a cab driver) made an advance toward him and that when he refused her she called him gay and insulted his manhood so he decided to send her this photo because he was angry. ok so this sounds so sick and wierd to me that some guy would be photographing his privates in his car and sending it to women he doesn't know. I'm just feeling really creeped out about living with someone like that. am I over reacting???
