Husband doesn't really like to go down on me

He acts like he does it a lot - will brag about being good at it (he is when he tries). I don't push him because he has some asthma issues and I don't want him to be uncomfortable.

But it's always been a precursor to penetration, which is cool. I just would love to be with someone who gets turned on from going down on me. I hear all these stories about men who truly love to eat, and I've only ever been with one man, so I don't have that experience.

The grass is always greener, they say. But I can't help feeling like I'm missing out, and then I start to justify it by telling myself I'm probably not attractive enough anyway, too old now, past my prime... whatever.

Anyone else have this be their situation and were able to turn it around or figure something out?
