I have a small mouth, and for some reason, my jaw muscles are always very tight feeling when I try and open my mouth up wide. Even my dentist has to use a different and smaller spacing device when taking X-rays of my teeth because of this.

Anyways, whenever I gave oral in the past, I found it difficult because of my small mouth, and the fact that it would get tired, and I would start closing it a bit too much for it to be enjoyable to the guy. "Too much teeth", they said. I also found the taste a little unpleasant and I've never gotten the guy to the point of successfully cumming via this way, and having a guy cum in my mouth sort of scares me because I don't know what it tastes like at all and whether or not I'll like it.

Anyways, the reason I'm bringing this up is because I'm sort of seeing this guy right now and this may come up sometime in the future. I want to be prepared. How do I make sure it's an enjoyable experience for the both of us? I have some flavored lube, would that help?
