Dear Em & Lo,

Lately my wife and I have been fighting a lot. I don’t feel close to her at all. The few times we do have sex in a month, I’ve noticed lately that when we have intercourse, something is making my penis feel “numb”. Whatever it is it really desensitizes me. My immediate thought is she is cheating on me and her new guy must use those condoms that make you numb and it’s staying inside of her and that’s what is making me numb. I’ve never noticed this until recently and we’ve been married over 10 years. What could this be?  Could this be feminine products she uses that is doing this?  Whatever it is, it’s only when I’m inside of her.
