My first relationship was with a girl - we were 17 and in high school. We had to hide it from everyone, then we were going off to different cities for university so we (she) called it off after three months.
Then a guy in my first year of university (18) - sweet guy but really naive and immature and started to get on my nerves which only got worse until I was repulsed by him, so I broke up with him (about six months), and he cried

Then about a year later (19), starting going out with my current boyfriend (almost two years - now 21 - and very much in love)
So not much experience for me, but enough to know what's out there, what I like and dislike etc.
I don't mind being single, but I'm always on the lookout - that's the fun of being single, checking people out and getting to know them etc.
