Always plenty of lube, and keep yourself nice and clean. When I was a teen I found out jacking off and not washing off each day had some issues that were not fun dealing with. Sometimes I have red rash for a couple of days. Us guys can get yeast infections just like the ladies do. That not a good thing to have either.

Not really a fan of lube wanks, I prefer dry wanks but just have to be careful on ending up with it getting too red.
