OP- try aloe for the bumps/razor burn next time. Real, 100% aloe or a slice of the plant.

Also, for future shaving needs, pick a good quality conditioner (I like Shea Moisture brand) and slather it on your personal areas which will be shaved. Let the conditioner soak in for at least 2 minutes. Shave using a fresh or newish razor, using Sensitive skin gel and foam it into a rich lather. Wash your razor with very hot water between each shave. After the shower, moisturize with a good quality moisturizer (Lol I like Dr Bronner's lavender lotion but aloe works great too). Good luck!
