I can only speak from experience (or personal lack thereof). So I CAN speak for guys. Anyone who tells you having sex with a willing, well built, gorgeous, young teacher, for a guy student, at age 14, is harmful, and ALSO should be punished for it (as you said), is a repressed whack job.
On the other hand, since you told ME to, YOU invert the sexes.
The kid is guilty too. He allowed this bitch to ruin her own life. May his weener rot off. 14 is plenty old enough to know wrong and right.
Would you pass this judgement on a 14 year old girl?
