I had a 'girlfriend' when I was 13 but I'm not sure that really counts
I then had a few dates and a couple of girlfriends when I was 18/19 but they were only short-lived and then nothing since. I'm now 26. I've had a few close girl mates but nothing more than that. I sometimes wonder if they were waiting for me to make it more than friends, but I am too scared to find out.
