So my SO likes to go down on me. Because he's sensitive about how I taste, I almost always run some water over my vulva area before he does it (I have a stronger taste/smell than a lot of women and it kind of gets to him if I don't). This morning, it became obvious that he was going to go down on me, so I washed up a bit before it happened. About five minutes into it, he asked for a break because he said his tongue felt like it was burning. Now, I am aware that the tongue is a muscle. Could the burning be due to some lactic acid that's building up in his tongue and causing him pain? Does he just need to practice more to get his tongue in shape (so to speak)? He thinks that the reason behind the burning has something to do with my pubic hair, but I keep it trimmed, so it's not like it's a jungle down there or anything. This reasoning of his makes me feel really self-conscious, like there's something wrong with me because I don't shave my vulva completely. Has anyone else had a partner with this complaint?
