I couldn't even comprehend sharing my hobbying life with my friends, in particular my women friends.
It is just something that is very difficult to discuss in an open forum. I guess perhaps one or two of my closest male friends I could see myself in a moment of weakness sharing with, and though I ultimately think they would keep it close, and not be judgemental, the risk is too great. Prostitution (or 'the hobby') is one of those visceral issues, where people are either in the mindset that prostitution is an aborrent and depraved practice, or that prostitution is okay. There's no middle ground on the issue for alot of people, there's far too much stereotyping and misinformation swirling around the issue, and people who have strongly held feelings one way or another, are highly unlikely to change their minds
For something that has no bearing on my relationships with friends, it's stupid to bring it up. For females, although there's many females such as blissful, and some TERBite's wives who apparently embrace the lifestyle, there's a vast majority who don't, and while some guys are open to the possibility of one day hiring a SP, or are themselves hobbyists in secret, there's very few females who can withhold judgement on the issue.
Besides, my social life and my hobbying are two separate things, and even if my friends were aware of my hobbying, I don't really want to get into any psychological discussion about why I hobby, or a blow-by-blow description. That's what TERB is for

Also, another factor, particularly with the females I am friends with, is that us being in our mid-to-late twenties, there's not as much tolerance and understanding for this type of thing, as opposed to twenty years for now, when there's more life experience on the table.
As far as relationships go, again it's a complete non-starter. I'm sure there's some people who are open about their hobbying with their SOs, and hell there's some people on here who allegedly see SPs with their SO. However, to most females it's an instant deal-breaker.
It's hypocritical, and harsh and I wish that there was more openness and frank discussion outside of the cloistered walls of TERB about it, but that's the way it is and there's no changing it anytime soon. On this issue, I'm not going to be an activist
