Hi, My boyfriend is a freshman in college and I’m a senior in high school. We’ve been together for 1.5 years and I’m going to visit him for his fraternity’s formal and beach weekend soon. Formal is like college prom basically and beach weekend is a weekend long party at a beach in bikinis and stuff. I used to wax my bikini line until this summer because it became very badly bruised and irritated. I’ve shaved it a few times and it always grows back within a day or so! I some how need the shave to last at least 3 days and don’t know what to do! Any advice?
