My wife and I provided our daughters, Heather and Meredith with birth control when they entered high school as well as king size California beds in their respective bedrooms so they could entertain their various boyfriends that they invited to sleep over.
Our girls are good girls and they never became pregnant. In fact they graduated from Harvard law school this year and are taking a year off to work with their cousins, Constance and Prudence, as call girls in New York before they join a Wall street law firm.
We are very proud of the girls and they always uses condoms due to our influence as proper parents. Even though the girls adore anal sex we know that they will be safe due to their consistent use of condoms.
If porn stars had proper parenting then they would not have a problem with disease.
