"So such wounds are really not prone to HIV transmission right?" Right.
"And about chapped lips in contact to any secretion coming from nipple?" Nobody ever caught HIV from kissing someone's nipples, chapped lips or not!
"I wouldn't worry for this life so fiercely unless it was connected to loved ones." Of course not. That's always the main fear. But it doesn't make the risk any different.
"Should I wait for 6 months for test and avoid contact with my wife?" Absolutely not. You should continue unprotected sex with your wife this very day. You cannot infect her with something you could not have caught. And in any case, the time to definitive HIV testing is 4-8 weeks, not 6 months. See

That will be all for this thread. I won't have any further comments or advice. Accept the reasoned, science-based reassurance you have had, think with your left brain not your right, and move on.
