My son...
Let the cheese of your virginity power you to great heights.
Start working out dude.
Get into it. Use graphs.
Measure yourself.
Eat health food that tastes like shiit.
Crossfit!
My story:
When I was around 20 I caught pneumonia and saw myself very skinny. This grossed me out...
So for the next three years I worked out twice a day, once for cardio once for weights. After the three years I stopped, but maintained my shape with very light/minimal exercise. Even today I still get compliments on my body 20 years later! Even if you are horrible at seduction women will bang you as long as you are not a filthy pig.
