merleniau I don't know if Fi rides horses - I should ask her, convince her to come for a ride with me after we finish work one day. Talk about a surreal experience.
Tully Mars I think it's if you have more then two sex workers working out of a residential building then it becomes classed as a brothel. Was a big hullabaloo a few months ago about a guy who dobbed his neighbours in for running a brothel out of the house next to his. Cops went and explained the law, they bought the house on the other side of the guy that complained and now 2 of them work out of there and 2 out of the original house, now he's in between two 'non-brothels'

There are definitely male strippers and prostitues out there though they tend to be alot shyer about their profession, espceially the Pros. I think it's because they can't guarantee a career working solely with women, every male pro I have talked to has at some point worked with male customers. I think they're more afraid of admitting to their mates that they're gay or bisexual then they are admitting that they're a sex worker. None of the guys I know through the business have had any major problems, a few women will attempt to grope them while drunk or a guy might be a little rough but people seem to be alot less insistent with a large muscly guy (the ones I know are all about 6 foot and BIG) then they are with women, Fi being a notable exception.
I don't have any problems with male sex workers, my issues with them in no way differ from those I have towards women working in the industry, as long as they don't cause problems for the rest of the industry and behave in a safe responsible fashion no prob.
As for the other parts of your question - depends on the circumstances, yes sometimes strippers do get turned on at work. Think about it, you're lying / standing / sitting there for 6 - 10 hrs masturbating. Every now and then you're going to react to it and that's not including the guys / couples who want two girls, as I'm bisexual those shows are always a little extra bit of fun for me
Then you have the girls who are exhibitionists, we have 2 at work who most definitely are and they get off on being wanted by every customer that comes in (or most of them anyways). It's the perfect job for someone that needs to be found desirable because you're in a situation where guys KNOW you're unattainable (or close to, there's always a few that ask for your number or give you theirs)
Some of the Pros I know do get off at work but they actually try not to. Alot of women become MUCH more sensitive after an orgasm and that's not something you necessarily want when you've got half a shift left. At the same time I've heard some friends complaining about Johns being obsessed with making them orgasm and they're just not interested, all they want is for him to finish and move on. Kinda cuts both ways.
