Please don't use sex as a reward to your boyfriend. Sex is a special act of love.
To me, I think you are to young. Speaking from experience, I am 27 & I lost my virginity 3 months ago. Now me & the guy have broken up. I thought he was "the one" but he turned out to be a jerk after it happened. NOw I'm working through my depression.
You are too young. I know it's hard with peer pressure & everything. Finish school, go to college, travel, enjoy life. You will find someone later in life.
