I have a similar backstory! Felt dating and kissing were gross throughout most of my tween and teen years, then felt overwhelming pressure and an obligation to “finally start dating already” in my 20s. I also met my gf online and have been together for almost 3 years, and before that, spent a long time Googling how weird I was for being an everything-virgin. We are definitely not alone! I know several people IRL who are still everything-virgins; it’s fine, we all have our own timelines and Western culture just has a habit of telling us to conform or else.
I wrote about my experience as a late bloomer too, if you’re interested in reading (no pressure!).
