My partner and I have been together for 6 years. We have a fairly active sex life (once or twice a week), slightly less than I would prefer but he has a lower libido than I do. He is also generous in bed, and makes sure to make me cum with his fingers at least once, generally twice, every time.
He seems to save oral for special occasions, such as my birthday or trips away. How do I ask for this more often? I'm unsure whether this is because he prefers to save it for occasions, or whether he doesn't really care for it and only does it to spice up the sex when we're in hotels etc.
I get that the obvious answer is communication, but I find discussing my wants during sex awkward, and I don't want him to feel as though I think the sex we're currently having is bad.
TLDR; how do I ask my partner for more oral, without making him feel attacked?
