My girlfriend and I have been dating for 11 months. She moved in with me two months ago. She was originally the one who brought up the idea of a threesome. She’s bisexual and I was totally into the idea of it. We spent over a month going through tinder until we found someone both of us thought was really attractive and fun. The girl came over and we all hung out the first night and just got to know each other. My girlfriend said she liked her a lot and she was super hot, which I agree.

Fast forward to a few nights ago. The girl came over and after a while of just hanging out we all decided it was time to try stuff. None of the three of us had ever done a threesome. It was awkward at first and I was definitely a bit nervous. It was hot watching the girls play with each other and then I got to play with them. The first problem arrived when I couldn’t get hard to do things to my girlfriend. Gf tried to get me going but it didn’t work. The other girl started to work on that and it worked great. Later on when it was my turn for oral my gf touched me a little and then did her thing. Well then the other girl went down on me after and it was 10x better than what my girlfriend does and it made me realize what actual effort during sex is.

Let me explain, I’m big, I’ve got great stamina, and every time with my girlfriend I spend a good 20-30 minutes getting her turned on and that’s not even half of what this other girl was like just a few minutes into playing. I can pound my girl for 20 minutes straight and nothing happens without the use of a vibrator and even then it’s iffy. I pounded this other girl for 10 minutes and she had the strongest O she’s ever had. That’s the first time I personally have made a girl O without a vibrator since I’ve only been with my girl and this other girl.

I can’t stop thinking about it now... about how good sex was with this other girl and how a little effort goes a long way. She got way more wet, she orgasmed, and she was really beautiful. I don’t know what to do here and I need advice. Any advice in general. I just feel like my sex life is missing so much now.

That's your polygamous nature kicking in. Your brain is like, "This is new, I'm spreading my DNA to new places." and so your body is reacting like you've just gotten out of prison or something.

Is it really so hard to believe? When you got with your girlfriend did you have a lot of options going on? Did you really expect her to be the best sex you where ever going to have.

There's always better in that sense, and what you're dealing with now is why most people don't invite people into their bedroom. Someone catches feels, and that someone is you here. Good luck going forward! I'd try keep that thing going for as long as possible, personally.
