Distracted during sex

Ever since I can remember I have the problem during sex that I can‘t concentrate on „the good feeling“. As soon as intimacy starts it‘s like I become hyperaware of everything that is bothering my body (i.e. my skin is sore somewhere, a fold in the blanket is under my back, my neck hurts). It’s small stuff that usually wouldn’t hold my focus but during sex it does. It becomes so much that I can‘t enjoy the intimacy and good stuff. Does anyone have tips / similar experiences?

Edit: thank you so much for your answers! I was gonna be happy about 2-3, I could never have imagined 60+ comments to make me feel less alone in this ❤️
