I think sex work should be legal and regulated to avoid trafficking and other health issues. General indecency shouldn't be allowed, like in playgrounds, parks, or where minors may otherwise be present. Private clubs, events, etc. should be fine. Governments should otherwise be uninvolved in our sex lives. It's none of their business.
However to answer your question directly, while I think it should be legal I also think it's sad when men use a sex workers services. I try not to, but I can't help but judge them. There's only a handful of reasons where I think its a persons only option. If someone feels like they've run out of options, it's just sad to me. What's gone wrong? Where's your confidence? Have you given up?
