I cant give him what he wants...

So here's the situation...

I cant seem to become comfortable sitting on my mans face... he wants me to all the time. If I'm tryna be sexy and tell him that he can have whatever he wants tn... the first thing he requests, is that I sit on his face.

For some reason, I just feel so vulnerable in that position. It has nothing to do with my weight, or any sort of body issues. I love getting eaten out any other way. But for some reason, I just cant sit on his face. It makes me nervous or something. Every time that I have done it, it turns out great, and i tell myself that next time there won't be a problem. But there always is. I'm always uneasy about it. Idk.

I tried to explain this to him. And he just doesnt get it. And I cant help but feel bad.

Anyone else relate?!
