I don't usually go cruising but last night I went to a place with glory holes etc and got a few BJs. The first was a young guy who wanted me to bareback him - I declined but he had already sucked my dick once and bit the tip. I think he meant to bite my PA and got the tip of my dick too. Then got two other BJs but didn't come until I JO'd alone to a video. Then I left. My question is if you can avoid STDs by doing simple things like wiping you cock with Purell or putting on anti bacterial ointment. After each BJ I went to the bathroom and washed my cock off but still I wonder. So I'm curious. Besides the obvious - abstinence - is there a way to avoid STDs?
