A word to the wise is sufficient
This is an interesting discussion, but another thought besides jealousy comes to my mind when reading it.
Our friend Dirk makes no bones about the claim that he drills as many of these girls that he can bareback. Which means that whatever one girl has (genital warts, chlamydia, herpes, syphillis, etc..), the subsequent ones also stand to get. Doing bareback with hookers is his preference, and he's certainly entitled to it.
But.....
This is precisely why I'd never dream of fucking any of these girls without a rubber - and even then you're running a fair risk of STDs. Caveat monger.
