Is low self esteem going to destroy my relationship?

So I'm a 20yo guy who's dating another guy at the moment. We've been together for about 9 months now. Both of us have been extremely happy together over those 9 months, but there's one thing that is putting a bit of a strain on the relationship from my end and it's worrying me a lot. I don't really know what to do about it.

The problem is my own self esteem. Recently, I went on a night out with my boyfriend and a few friends. While we were there, two of the girls I know wouldn't shut up about how attractive my boyfriend is, and one of them went on to tell him he's 'her favourite' and how grateful I should be that I'm with him. I suppose from their point of view I was supposed to take this as a compliment, but the truth is it really knocked me quite hard. It's not the first time I've felt inadequate or my self esteem has been low. Most the time I'm fine - yes, my boyfriend is attractive, but I never used to compare myself to him or feel he was better than me. Now, every so often, it bothers me a lot - I'll feel like I'm less 'put together', or less attractive, and that he seems to one-up me whenever I try to do something (which isn't intentional on his part btw, it just kind of happens).

He thinks a lot of himself, but the important thing is I know he loves me and thinks the world of me - I just think the worries and my self esteem issues will start to cause problems, and they are getting to the point where it is making me feel miserable. I don't want us to grow apart because of my lack of self confidence, but I don't know what to do or how to let go of it. How do you deal with this?
