Couldn't feel anything 😔

So we just made love for the second time. The first time was in cowgirl and I didnt feel much then, just some discomfort from my IUD. Last night was the 2nd time, and we did doggy, spooning, missionary... but still I didnt feel much. Like I loved the intimacy and warmth and passion, but physically it was like numb inside?? I was nervous ofcourse, but SUPER slippery wet. My boyfriend isnt even small, I'd say he's average. Ive had way smaller before. But I think I'm getting way too slippery or smt. It didnt take him long either time to cum, but I worry that I'm loose or something (I'm in my mid-20s) . Should I be doing kegels ? I want to be tighter for both of us.

Any advice is really appreciated 🙏🏼
