I was in Bangkok 2 years ago. If helpful, I stayed at the Well Hotel Bangkok on 10 Sukhumvit 20 for about $90/night. It was a nice hotel with a swimming pool, they didn't care when I brought girls back and when I did, the front desk held her ID and would call up when she left to make sure everything was ok. This obviously dramatically limits the risk you get scammed.
There was a nearby sports bar that now looks like it's going by the name Robin Hood that had a good beer selection and a few attractive freelancers waiting around for clients. There is also a small side street of Sukhumvit 20 with a few gogo bars, though I didn't go into any of them and can't vouch for them. It's a short walk to Soi Cowboy and also a blowjob bar called 7-Heaven if that's your preference.
To be honest, I think Hong Kong is better than Thailand for hobbying, though at a slightly higher price point.
