I would have left no matter what, they in fact by their omissions lied to you (in my opinion). We had a similar situation this last weekend. We normally don't play on impulse, but we had just finally got the hot tub fixed, it was my birthday weekend...just wanted to have fun!! LOL, when to make a long story short this couple about 40 min or so from us, had e mailed wanted to know if we were doing anything Sat. nite, they weren't. So we thought why not, emailed them back and talk a few, told them we had a pool, hot tub and bar, come over and hang out. Seemed great, things went well, we got naked and got in the hot tub, well he was a two minute marathon man (if that)... I was like on nooooooooooo, this can't be happening......then he moved to the other side of the hot tub and told me he was thru, I was stunned, she was wanting to go hot and heavy with my SO, I went in the house to the bathroom, came back, he had joined in with my SO and his, I just looked at them and the total scene...told them this isn't working out and you need to leave. They were not up front with us, he after I asked them to leave told my SO that he can't last long, that is why they swing??? Have you run into this, also? I felt totally used and not wanted.
