I'm 22 and never been in a relationship, never been on a date, never kissed anyone, so you have no reason to worry just yet! But I will admit it can definitely be hard, I tend to keep it a secret now because I am embarrassed and don't need the questions of why have I never had a relationship/am I a lesbian/do I want to be set up with someone/have I ever done this/have I ever done this/have I ever done this, etc.. It's really not a story I want to get into, you know? I don't even talk about it on here because I'm too ashamed of how I feel.
So don't stress just yet. If you feel your relationship issues are caused by something more, then get some help if you can. I wish I had, maybe I wouldn't be as terrified as I am now. Save yourself from ending up like me!!!
