Intimacy and Thoughts

I’ve been working on my relationship with my husband and it’s going great. But an area I am struggling with is intimacy. I enjoy sex, but I have always avoided intimacy. I don’t have a tragic past or anything tangible to work through. I’ve tried to do downloads on it, and I’m having trouble even figuring out my unintentional thoughts. Can you share scenarios that you’ve learned from past clients??? Some intentional thoughts to help me would be great.
C-intimacy (maybe even the ultimate vulnerability)
A-I avoid intimacy
R-I do not have an intimate marriage
