Need advice!!! 😩

So for me, this is super embarrassing for some reason. But it's something that makes me uncomfortable with myself, and its super annoying. 

I get suuuper bad pimples on my butt... Yup thats what I said, on my butt!! Its so bad that I literally have scars and the pimples take forever to go away & clear up. Ive had these ones for just about three months now, steady. They aren't healing fast at all. And as soon as they do, they eventually come back anyways. Im super self-conscious about it. Especially during that one on one time with my bf. It makes me not want to do anything at all, i donteven feel  comfortable changing in front of him or anything. Or even wearing a bathing suit in the summer.

Ive tried scrubs etc.. Even putting polysporin on it to try to help heal it quicker.. I just dont know what to do anymore... Anyone have any advice or have this happen to them? :(
