food for thought:

women who are 18 and say they don't want kids are told they're too young to know better and will change their mind

an 18 year old girl doing porn though, is seen as mature.

Neither TEENAGER can legally drink alcohol. The difference is men use one to jerk off

Furthermore, an 18 year old girl doing porn is exposed to an industry with heavy drug use, rape, incurable STDs, and likely has ruined her job prospects and is at a much higher risk of suicide by bullying. Society deems this danger acceptable because she is serving penises. Tada!
