Waiting until marriage

I’m sorry if this is a bit vulgar but I made the decision to myself and more importantly God that I would be waiting to be intimate until marriage but lately I have had some anxiety in my head that oh no men my age will want that or that we won’t be sexually compatible because for me sex is very important but I am only willing to give that love and pleasure to my husband, basically I just need some guidance and words from my brothers and sisters in Christ
