so she wouldn't let you suck it covered? that's odd.  and is it safe? probobly not that's a risk you need to decide on taking.

There are no stupid questions-

OK, sometimes there are, but this is not one of them. IMO, ladies fall in to three schools of thought on this. Some are all about saftey, and if it is not covered, it is not happening. Others are ok with you giving them BBBJ, but not the other way around, you have to suit up, but not her. Finally, there are ladies that both give and receive BBBJ.

Having participated in all of the above, I am a fan of the later, and I am not to worried personally about the oral aspects of STD that way. You should do some research on the subject and get better informed so you can hobby with peace of mind.
