I also agree with SJ on this, whether you disagree with HP on his choices, both in the ladies he prefers and the services he seeks, at least he is honest about it.
At the end of the day we are all adults on here and we all must take responsibility for our own actions. If no-one offered bareback sex then those Punters who wanted it could not legally obtain this service. Besides the ladies HP chooses are not what you could call naive innocents who don't know better.
What is worse, consenting adults who, knowing the risks choose this option (which in HP's case I believe is the case) or WG's who offer it because their pimps tell them they have to end of!
TO look at it all another way, I could argue that theoretically smoking, drinking and consuming hard drugs possess as big a hazardous to health as bareback sex, they may not (I don't have the statistics to hand) but I choose to only drink out of those 3 options myself at a moderate level.
