Hubby and I just bought and moved into a house that came with a Hot Tub/Jacuzzi/Spa.(What's the difference anyway?) We have made love in it twice now...very interesting...it's good that both of us know CPR. LOL We will just have to keep practicing. Anyway, my question is this...The manual and video for the spa both warn of bacteria growth in he water and keeping it clean, etc. Well, is cum in the water going to cause bacteria growth? Should we drain and clean it everytime we have sex in it?
