hello
I think it is natural for you to be jelous. I think everyone is jelous of something. I was jelous of other guys (especially my brother) when i was growing up. But he was jelous of others and i think we are all jelous or at least we kind of envy others no matter what. Now, as a pretty much completely transition guy, lots of people are jelous of me. Especially in the locker room! They think my 6.5 inch flaccid penis is 10 when its hard, or they are jelous of my muscle mass. They have no idea how hard i worked for both of those things. So I can be jelous of them for being born with everyhing in the right place, and they can be jelous of me thinking i won the genetic lottery.
That baby will grow up and see someone else and be jelous of them for something. penis size, hair line, money, teeth.... etc. just try to keep in perspectiv that everyone has something that makes them feel inferior.
I hope that makes sense or helps or gives you some insight.
