would you rather have a girlfriend who is a hot milf but she is in her late 30's to 40's, and has her tubes tied (so you can blow your load inside her without a condom with no fear of pregnancy).

OR

would you rather have a smoking hot young college aged girl (she's a 10), but her tubes are not tied, so there is risk of pregnancy. You will always have to use condoms or risk pregnancy.

Pick your Poison.
