Is it odd that I want to be a mother more than I want to have sex

It's just that I want a baby real bad but I'm only 14 and I don't want to keep the family tradition cuz my sis got preg at 16 and my cuz at 13 and I don't want to follow in there footsteps but I don't want to have sex really bad now that I realized how many diseases you can get drone sex if it's unprotected but I want a baby!!!!!!!!!!!!!
