If so do you invite people round to share it with? I would find it rather creepy sitting in it half naked with friends or neighbours. I never would, I wouldn't feel comfortable.
No but I have been in hot tubs. We all had swimsuits on not much different than being in a pool. One was at a ski lodge and relaxing after skiing with drinks, another was at the end of a pool nice to sit in in the evening
What also put me off was a man in loose shorts who insisted on standing with one foot on the bottom of the hot tub and the other on the seat whilst he was talking to me and my wife. We could see his meat and two veg and it wasn't a pretty sight. I'm sure he was fully aware of what he was doing.
