Help Me! My Girlfriend Has Refused Me Doing This One Thing During S*x and It's Killing Me

 

Since our son was born around a year ago, my girlfriend will no longer let me give her oral s*x, although she will still give it to me.

 

I am 23, my girlfriend is 20 and we have been together since our teens. Whenever I try to give her oral, she pushes me away.

 

This spoils the atmosphere of our lovemaking because it makes me feel like I am abusing her. I love her and the last thing I want is to upset her like this but I miss the intimacy we used to have.

 

Do I keep on trying or should I simply give up?
