My boyfriend needs to see everything with other women

I am very scared. Everywhere we go together. I cannot relax. My boyfriend loves high heels and women's clothes. He also wants me to wear high heels every now and then. I don't like to wear them.
When we are on the marketplace, he is very interested in the high heels that are there. I feel forced to wear them.

When he sees a woman in a legging, I also see something happening in them. He has to see everything... it makes me feel so insecure... He also likes very sexy clothes. While that doesn't feel like me. They are a bit slutty. I feel like a fall short.

It's a bit of a chaotic story. It's also a little bit too much for me....
