Would this have motivated you?

One of my biggest irrational fears is my teenage son getting someone pregnant too young or unplanned. I know I started experimenting really shortly at 14 with a long term boyfriend. I did not lose my virginity till i was 18 though. Even then I did not use a condom the first couple times even being properly educated. I got fortunate that I didn’t get any surprises. Anyway, my son is also properly educated but I know things can happen. I’m thinking about a tactic I saw my aunt use with her son telling him that if he didn’t get anyone pregnant and if he didn’t get married before the age of 25 she would buy him a new car. He’s accomplished and got his car. Sorry for the long post before the actual question, if offered would that proposition have motivated you to be more careful having sex?
