How old are you when you had your first serious boyfriend?

Foremost, I have to say that I refrained from or avoided any romantic relationship with the male gender until I graduated from my college studies. I love and respected my mother so much that I tried my best to heed her advice; to not engage myself in romance before finishing my studies. Personally, I had my first serious relationship with a guy when I was in my early 20's. During that time, I was already employed in a local bank. In fact, we were officemates and our relationship lasted for almost 4 long years. But it turned sour because he had an illicit affair. I'm not going into lengthy details but after a few months, I met another guy and our relationship lasted for almost 3 years before we both decided to tie the knot. At present, we are already married for more than 5 years and we currently have 1 daughter for a child. It took us more than a year before I was finally able to conceive and bear a child.

..I was 18.. and I thought that relationship would work out.. It was actually going well but I decided to put it off because I think I we are still too young to be in relationship.. we are good friends now.. I got married earlier.. He will get marry soon..
