Last night the gf and I went to a swingers party and had a blast. We ended up getting naked in the hot tub and fooling around a bit with a couple. They were super respectful and every one gave consent beforehand.

At one point the female half of the couple wanted to sit on my lap and my gf said go ahead just no penetration. We made out and felt each other all over. I fingered her and she jerked me off. Then she made her way over to my gf. I was super excited to see my gf hook up with someone. She's 100% bisexual, and I gave the green light to my gf and the woman. They started making out and sucking each other's nipples. Then they started fingering each other. It was so hot and something I've been fantasizing about for years.

I guess the woman and her husband started having sex and she told my gf to get on top of me and they would make out while we had sex too. The thing is that for some reason I couldn't get fully hard. The more I tried to relax, the worse it became. The funny thing is that I've had sex in front of people before, so I wasn't expecting it. Many years ago I had an orgy that I couldn't get hard for either.

My gf was super understanding and stopped everything that was going on to talk it out. I told her that it's ok. I thought that was really cool of her.

We finished out the party by having sex on the couch in the living room while people watched. For some reason I was able to get hard for this, although I couldn't cum. She is more comfortable in these situations and she did cum. I'm not really sure what it was specifically about the other situation that gave me performance anxiety.

We both had a great time and want to go back again and explore this more. I think maybe just more experience in these scenarios will make me more comfortable and ease up the anxiety a bit? I don't want to find myself in a situation where my gf is getting fucked and I can't get it up.
