I'm very conflicted on if I should submit to becoming a beta male. I have been in 2 previous relationships and both of my girlfriends have cheated on me. The first one was with a white guy and the second was with a black guy. Both of the men were very well hung. I'm currently in a third relationship and I just caught my girlfriend cheating on me with the same black guy my previous ex cheated on me with. I'm pretty sure it has to do with my penis as it is only 3.5 inches. All the girls I've had sex with look very disappointed when I pull my briefs down and they've asked on multiple occasions if it was in. I've tried to please them other methods, but there is nothing that can substitute for a large penis apparently. My girlfriend doesn't know that I've caught her and I'm wondering if I should stay with her and just accept that the women in my life will need other men. Should I just accept a cuckold status?
