My boyfriend that I've been dating for almost 4 years now never goes down on me. I constantly go down on him whenever things are taking too long and my vagina can't handle it any longer. The last time he did it he said it tasted bad, and I couldn't tell you how long ago that was. I've tried doing things to make it taste better like eating pineapple and I'm a very clean person so that's not the problem. Should I tell him to get over it and go down on me or not bring it up at all?
