LOL are we supposed to take that question seriously?
All I'll say is that if your prime concern is whether you're "man enough," odds are you're not. There are several things that help in pleasing a woman in bed. Ego isn't one of them. And the same goes for pleasing her in a relationship generally.
Also, if you think you're unworthy, that, too, means you're probably not. But the same is true if you are fixated on believing you are and bragging about it. If it's all about you, that doesn't go over well.
