I have been dating my girlfriend for about 9 months now and we have been having sex and I have wanted to have sex in my hot tub for the longest time, but every time we try, it doesn't work. I will be sitting in the hot tub and have a hard on and she will be on top, but it won't go in her vagina. It seems like it is not wet enough to go in and I was wondering if there is anything I can do to make it go in so we can have sex in the hot tub. I thought maybe a condom would work, but I haven't tried it yet. So, I was wondering if anyone here knew of any techniques that would allow us to have sex in the spa. Thanks.
