When You Have Sex, Do You Have To...?

No , of course not..but let me tell you most men do like it "cleaned up" a little bit...but this is up to you its all about what you feel comfortable with..

Some men like hairy. the hair traps natural phermonal odors that are owner specific to each woman.  These odors can be very simulating.  Like everything sexual there's no right or wrong, only what u and ur partner desire.

No you don't have to but i think that most men like it when its shaved/wax. If you don't want to shave it all off just try giving yourself a trim and stay nice and tidy down there believe me guys love that because if it ain't shaved then they know your keeping yourself maintain and groomed down there but its really up to you and what your comfortable with.

I think it depends on the culture. In most Asian countries, men will think you are weird if you shave all the hair, but in western coutries, it seems men like you get it 'cleaned up'.

Does shaving hurt

I really like it shaved/waxed. You can lick and nibble on everything around and not get a mouth full of hair. The whole area is sensitive, so I like to take advantage of that sensitivity.

You don't have to if you don't like the idea, but a lot of couples prefer it. There are many possibilities - from just trimming and tidying up, to complete hair removal, and anything in between.
Personally, I find it more sensitive to be completely hair-free down there, not to mention cleaner and more hygienic.

Waxing is initially more painful but you get a smoother finish, it lasts longer, and there aren't so many problems with ingrowing hairs during regrowth.

Sometimes. Some guys like hair.
