Your talking to a crazy person. Everything goes through the drugs chemical filter. However if you look at the attached google side effects, it mentions "decrease sex drive, impotence, and difficulty achieving an orgasm."
So yea, he is having difficulties with you, but he is also working harder when he masturbates. Try getting on top and working him while he is relaxing. It may work, but make sure that you have an orgasm.
If nothing else, you will be satisfied. The other thing is to look up the side effects of Lexapro then call him over to see if he is experiencing any of these side effects. Then point out item #4, and say that could be effecting us.
If so, he may have to try a different medication to control his issues. That is ok, many people try lots of different drugs to find the one that works for them. Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
