Am I looking at me? 😂 Seriously, that's exactly how I would describe my situation even down to being rejected for the transvaginal exam when I was suffering crippling cramps. It's like I'm reading a comment from myself!
Anyways, I'm rambling. My apologies. I just wanted to let you know that you're not alone or some anomaly. So many of us are in the same boat including me. I stopped caring about the social pressure a very long time ago because I sat back and asked myself 'why would I want to have sex now?'. When I realised that none of my answers were solely and completely 'because I want to', it took a huge weight off my shoulders. All my answers were related to how others viewed me but the decision to have sex should be solely about you. You don't have to do it just because those around you are doing it. You haven't found someone you're willing to trust in that way, and that's absolutely okay.
Just focus on doing the things you love, being yourself, and all things will fall in line. There's more to life than sex and relationships. It's not some finish line you must cross at a certain age.
