I did it when i was 17 for the first time.I had been with my bf for about 6 mths and it just happened it was all good and felt right at the time as i did stay with him for almost 5 years.None of my friends at school had sex by then i was the first one.You wouldnt believe this but i also got caught by my mum the first time(not in the act) she found the condom the silly bugger put it under the bed and when she was cleaning she found it i was so very very embarresed and she took me to the doctor and made me get on birth control.
