Terrified of the hymenectomy

I have a microperforate hymen and a few months ago my gynecologist recommended I get a hymenectomy. At first I was 100% against it because I found it innecesary, since penetrative vaginal sex isn't the only way to be intimate. Lately I've been considering it a bit more, even starting to plan it. Just now I was looking up the procedure because I want to know everything they're going to do to me before it happens. I was stupid and I looked up some pictures and just started crying. It looks horrifyingly scary, I didn't know there were stitches involved. I'm still crying, I know it's supposed to improve things but I don't know if it's worth it.
