If he is, he is not a safe partner. Best of luck. And i have never gotten pg. You have also put yourself at risk from any STD he may be carrying. Please use that chance and protect yourself.
Pubic hair is natural, healthy and beautiful.
Many people prefer a partner with natural pubic hair, and only a jerk would think less of you for it. If you want to do some trimming or shaving you can just trim it a little with scissors or a mens facial hair trimming kit, or shave the areas you feel like shaving. If you want to shave, soak in a warm tub and use a gentle shave gel followed by gentle facial lotion. Shaving rash is common and sometimes cant be helped, just shave in the direction of hair growth and apply neosporine if it still happens. Otherwise, just comb it a little so its not tangled and there are no stray hairs, and enjoy.
