Feel a bit strange

I was having sex with my boyfriend. Usually, there aren’t any complaints....

But about 5-8 minutes in, I just felt like all of my emotions went down the drain. Everything just felt numb, both emotionally and physically. I couldn’t speak or process anything that was going on around me, like I sort of blacked out in a way.

I didn’t tell him right away but he knew something was off.

I stopped and I asked him if we could continue another time. He said yes and finished in the bathroom.

I just feel so weird about it because it’s never really happened before. I’ve been feeling like this for more than an hour now and it’s a bit concerning. I’m prone to anxiety attacks and bouts of depression, but never during intimate moments.

Any suggestions, info or comments will be appreciated
