humans want to impregnate and be impregnated, thats kind of just biology... the concept of "safe sex" is relatively new, but we're hard wired to find procreation erotic, you are bound to find many girls including myself that think its sexy because its literally normal, as vanilla as it gets.
Non-con creampie / etc falls into the catagory of danger and lots of people like danger if you haven't already guessed that is also something arousing to some!
