Don't listen to all these 'unverified" people. None of them have any pics on their profile at all. On this site we have hundreds of time told people to get verified (which is super easy) so that fellow site members know with whom they are talking. In absence of being verified you should consider that the person on the other end with a high probability is fake.
As far as the "unsecure male" is concerned you should just dismiss all these nonsense advice they are dishing out. Being in the lifestyle to bring more excitement to it sexually and bringing you and your wife closer to each other doesn't mean that your wife should go and get pregnant by another guy whom with all certainty will not be around to raise that kid. Parenthood is serious business and you should NOT mix your sexual desires with the challenges of a having a baby your wife conceived with another man. Having had 3 children I know that it is not an easy task and full of challenges. Now imagine that you have a baby to care for who is not yours and was only brought into this world because she just cared more for another man to carry his baby. I am sorry but this is nonsense and inconsiderate behavior. The size of your penis doesn't have much with your ability to ******* your own baby. They can harvest your sperm and place it in her cervix or uterine cavity, I am sure you have heard of artificial insemination. It is upsetting that some wives are using the lifestyle as an excuse to "cheat" on their husbands. If she wants a baby with another guy, please keep the door open and hand over the divorce petition to her on the way out!
