Mohamed,
I'm sorry I am the only one to respond, all I can tell you is what I personnaly have tried. Yes it does hurt sometimes to have sex because of the friction and our sensitive and sometimes scaly skin. If you are experiencing pain/raw spots try a lubricated condom. If you don't like condoms and are practicving another form of birth control use a lubricant designed just for things like this, off hand I would say KY jelly. Don't use vaseline, it doesn't dissolve easily inside your partner and can cause infections. I don't know if you can get these products in your country but it is all I can tell you. Keith.
