Does it hurt? No... 90% of the time it feels really good. The other 10% of the time it can feel a bit uncomfortable and scratchy for the first few pushes. It all depends on your partners moisture level. Basicly if the man does the foreplay right, it will feel good 100% of the time. If the woman is not as turned on as the man, it can be a bit uncomfortable until the womans moisture level increases, or some other lubrication is aplied.

A young, fit and healthy man has no need to worry about increasing his sperm count. Nature will ensure his sperm count is high.
If you mean 'panties' as in what i guess is your vagina, then no. When i was young i got curious about that 'area'. If you just rub it then it shouldnt hurt unless you do it alot.
