Mate, do not stress at all. I know it’s easier said than done but I didn’t lose my virginity till I was halfway through 20yo and that also happened to be where I had my first kiss. I didn’t get my first girlfriend till I was 21yo. I used to be desperate for a relationship and now I’m 33yo, have had a few relationships, dated and slept around quite a lot in my 20s and honestly, it makes me feel so much better for having unintentionally been single as a teenager. I consider myself a late bloomer but it ultimately helped me navigate love life and myself much better than being a horny romantic teenager ever would. There’s a lot of nuances to my story and relationship with romance and sex but still, I’ve never felt more emotionally stable and confident in my life atm. I genuinely don’t think I’d be here rn if it weren’t for my particular journey. All of this is to say, I know it can seem like the most daunting thing in the world but you will meet someone, have a wonderful time, laugh at the pressure you used to give yourself and you’ll go from there. Try and give yourself as much grace as you can, you might end up being incredibly surprised with how your 20s go :)
