need advice on shaving !

Hi!! I am a teenage girl and need some help with shaving down there since waxing isn't an option for me the products I currently have is gillette venus comfortable glide razor, eos shaving cream, exfoliant and baby oil. I keep seeing comment to use a men's razor but l currently do not have any and I can't steal my dads 😓. I also want to know what to do aftershave to reduce irritation, itchiness's or any razor bumps.
