When we were dating, and during our first couple years of marriage, my wife enjoyed having oral sex performed on her. Lately, she just doesn't seem to want it. Instead, she much rathers vaginal/clitoral finger stimulation prior to sex, as well as a good amount of nipple stimulation (nips always seem to be on the top of her list). However, she spends nearly all of our foreplay time performing oral on me while I'm manually stimulating her, kissing/sucking her boobs, etc. This, I certainly don't mind in the least. She says it helps get her in the mood. When I ask her if she wants oral, she says that she "really hasn't been into it lately" and makes little conversation about it. I not claiming to be any type of professional cunninglingist here, but I'm starting to get a complex that I'm not skilled with the tongue. Any thoughts? Please help.
