shaving rash

male shaving

Im a male and i think that long bushy pubes look unsightly and that if my girlfreind shaves for me why should i not return the favor. but the thing i tend to always get a rash and it will grow back 2 stubble in like a day so was wondering if there is any hair removal creams or whatever to help out and any way if stoping it from comming back in a hurry?
