It could be as simple as the fact that before you had intrusions or interruptions so had to be more careful and that was a turnon. I've know of several people whose sex lives changed once they moved in together. I woulnd't say it's a deal breaker or reason to end the relationship. It is however a great chance to sit down and talk about what has changed.

Dear Mike!
While sex is certainly not everything a relationship is, but it plays a role - and not a minor one. First of all, I'm convinced you should speak to your girlfriend - it might turn out she knows that an issue exists, and you'll be able to figure it out.
Start the convo calmly, without any hostility or showing hurt - that way you will ensure she won't think you're trying to break up. You have to make a decision together, you shouldn't just build assumptions. It might be libido incompatibility, it might be just routine - like it was for my husband and me.
Give time, show patience - if you love her, and she loves you back, it will either work out perfectly or end in a way where no one gets hurt. Hopefully. Please keep us posted - we're here for you.

Hello. I voted for you not to end the relationship. You clearly love the girl, and the fact that you're incompatible sexually is sad but not tragic. I also vote for an honest conversation!

Had this problem with my second girlfriend - it was a first bicurious experience for her. At first she was really eager and lustful, and later on, the spark just went away. However, for us it was because of the messed-up idea she had in her head - she was not gay, we ended up splitting up and it broke my heart. Low sex drive can be a consequence of many factors. Maybe she's stressed? Maybe she wants to try something new but not ready to reveal it yet? The only reason to call off the relationship is if you are both sure there's nothing you can do to save it. I assume it's not the deal here. Best of luck.

Thank you, everyone. Really helpful comments. Getting ready to have the TALK this week. Funny thing - I actually ordered one of the new rabbits from EF and she can't lay it down not even for a night. It doesn't always come to us having sex, but I think it's progress. Who knows? Will keep you guys posted.

I talked to her you guys! Sorry for keeping you hanging for so long though. Just as I feared, she started crying at first. But then I managed to get through to her, I explained that I DIDN'T want to break up. Then we got into a fight because she thought I was insinuating an open relationship. To be honest, I thought about it, and told her just that. We took some time to cool off, and then proceeded with the conversation in the most shocking way for me. She started saying that she read about libido incompatibility somewhere and she's afraid we might have just that! Then we realized that we've been reading the same article, having the same concerns, I just didn't have the guts to talk to her before it got out of hand. We sat through it and talked through it, and I guess I'm fine - at least for now - with how things are. We promised each other that we'll try to spend more time together - it might make more relaxed and - with enough luck - more horny?
I know that I won't risk this relationship over having sex more often. Maybe there is something wrong with me or with us, and maybe I'm super cheesy, but whatever. We'll work it out.

Thank you all for advice and support -LOVE this community
