Safe sex is definitely something to think about it, but I think you might be subconsciencely using it as an excuse not to make a move. Don't fall into this trap. Wrap your junk and do the deed without thinking about it too much. I raw dog more than I should, and do the "pull out", but I'm also an idiot.. so don't listen to me LOL. Wrap your junk up and don't worry about it so much. Be safe and test regularly, that's all you can do. MOST of the stuff you catch can be cured with a simple anti-biotic.. I've had it, other guys here have had it, thousands of others have too.. it happens, and if you're having a lot of sex, you should just expect it at some point. Be safe, but don't let the fear of STDs destroy your sex life.
