I had sex after varicocele surgery 10 days ago and my testicle is in pain when it is touched, is this because of sex?

Here are some ...: I assumed, indeed, this question is pertinent to a man. But, some pain 10 days after surgery can be still expected but it's fine to wait and see as long as slowly but surely getting better day by day. As to if sex-related, only personal experience can tell, but if suspected, stop more sex and see. If still in doubt, see treating Doc timely.
