Desogen and pain thanks

I started taking Desogen about a month and a half ago and in the beginning I didn't notice any side effects. About 2-3 weeks into taking it, I realized that my sex drive was very low, and unfortunately it is still low! It's extremely frustrating not only for me, but also for my boyfriend. I then become very stressed out because I know my boyfriend is frustrated with me. I have also noticed that I am quick tempered a bit more lately, and I'm more sensitive resulting in me crying more easily. A side effect that I have not read in this column is one that I may be experiencing. For almost a month now, I've had a burning sensation every time my boyfriend and I are having sex and I'm not sure if this is a result of Desogen. I hate it because when I do want to have sex I can't because it burns so much. If anyone else is experiencing this pain and taking Desogen please let me know. I'm going to the doctor soon but it would be helpful to know if anyone else is going through such frustrating pain. Thanks!
