<human>: Sorry for any errors, it's 6am and, I haven't slept, and I'm on my phone. 

Back round: my boyfriend and I have known each other two years and have been dating for about a year. We just recently officially moved in together (at first he was just staying at my apartment but now he's moved his things in and applied for jobs using this address.)

Over all we have a very loving and sexually satisfying relationship. he's the strongest connection I've had in and out of the bedroom. 

We were hanging out on the couch last night and we were on Reddit (his account.) I saw that he has commented on a nude of a woman: "The things I'd do to that body." Now, honestly, that's not bad in my opinion. We freely talk about women we find attractive. We are always open and honest about sexual desires. 

What hit me (like a ton of bricks) is that I'm his only lover. We have talked about the long term loosely, like getting a dog and children way down the road. But here is where I need the advice: can I be his only lover? Is it selfish to expect a man is his sexual peak to not explore and see what he likes? I did a lot of experimenting at 20, am I just holding him back? 

I opened up to him a little bit because he saw me get visibly uncomfortable a few minutes after seeing the screen. I told him that I was concerned that he was being held back sexually. I suggested a break so he could explore. He freaked out, told me he loved me and that I was the only one. It got heated and now I'm just sitting up in the living room thinking about everything.

Can you give me the gist of the text in a nutshell?
<bot>: Saw a comment on Reddit my boyfriend posted, brought up insecurities about being his only lover. I suggested a break and it made everything 100x worse.
