So my cousin who is 16 asked me if he should shave and what he should shave. We are pretty open to things like this and he kinda looks up to me like an uncle. Hes straight but is getting sick of a bush and wants it to look tidier. But I don't know what to tell him. Should he shave his ass and gooch or just trim the pubes above his dick? What is probably the most suitable shaving advice can give to him??
