For context, I am 19 and started having sex when I was 16. Sex has since been a big part of all my prior relationships. She is 21 and has only even kissed one person before me. Additionally, she is a shy/reserved person and is made easily embarrassed when sexual topics are brought up. Before entering the relationship, this was a concern of mine and I wasn't sure if we could be compatible. But other aspects of her personality and the way she treats me outweighed that concern. I felt that we could grow in this together, and I didn't mind the idea of "taking it slow".
Now, I've never had an issue initiating, but I have never been with someone less experienced than me, much less someone with zero experience. Any tips on good ways to start? Anyone else go through something similar?
