Safe sex.

So obvious that is a big deal for me. My boyfriend is away for awhile and when he comes back i want to give him my v card :3. I will definitely make him wear a condom, but my concern is when i give him a bj, you cant really do that with a condom on. i have a few questions like what are my chances of getting an std/aids/hiv throw a blowjob and if both partners are clean and virgins how does one get contract those diseases?
