What is the best way to remove pubic hair around penis?

I've shaved my pubic hair that brought me out in a rash, I've used hair removal cream that made it go sore for about a week not had them waxed yet. I'm sick of doing them I like it all smooth down there and it makes it look like my penis is bigger than it is. If I get waxed I'm more than likely going to get a hard on will that be ok for the woman who's waxing me.
