Help being naked

Any advice for feeling more comfortable in your own skin while naked? Or in swimsuits? I’m 25 and at a healthy weight but I have trouble feeling comfortable when I’m naked and it distracts me from enjoying sex. Im definitely a late bloomer and have filled out the past few years, but most people would say I’m tiny. I think it’s more of the adjustment to filling out that I’m struggling with. I don’t have an eating disorder I’m just super self-conscious of my body.
