Just went to Guangzhou and Shenzhen over last week. The WeChat nearby people don't really work lol.
I've managed to find Telegram Groups but you would need to know Chinese.
I was with my wife for most of my time in Guangzhou and Shenzhen so couldn't taste the hotel/massage parlours.
There were a few I wanted to test out but couldn't get out.
I did go to Tenz 24 Hours Spa with my wife which was the old Water Cube in Shenzhen.
Had two full body massage, the first one the lady was middle age, wasn't a looker but I think she was enjoying her time touching me and I felt that she was riding me on my back when she was rubbing my back with oil (dry humping). Trousers were on but rolled up there is a window on the door so you can't do much, but she was having a feeling of my thighs up to my balls and when massaging my stomach she cupped my nipples and chest.
No special offers given afterwards, probably a good thing saves me from regret afterwards (I can't say no to extras).
Based on my first experience I thought maybe I need to give suggestions and wanted another go. Plus I just had a head massage in the massage hall, the ladies there was hot 🔥 and I needed to used the massage room to sleep over night)
Second massage was from 2.00am until 3.30am very late, the massage lady was about the same age as me (late 30s early 40s). She worked in the place for 16 years even when it was the brothel that was called Water Cube bathing / massage spa shop. I've given every hint by asking about the old brothel etc but she wasn't going to give anything extra. I think within the 24 hours spa you won't get any action. It was quite funny when we talked about the Old Water Cube Spa, she said she liked the change, at least she get younger more handsome men in, before it was just all middle age and very old guys, coming for the brothel.
DM me if you want the Telegram group information and you know your Chinese !
