I asked a similar question about how many people maintained their belows.
Whether or not you think you should keep doing it is up to you. I guess the reason you would do it is for someone else, so if you arn't getting any action then is there a point?
The way I look at it, would you like it on a guy? my answer: hell no, i like to have my fun with him and I don't want any hair down there, none.
Do you want any oral in return? if so, it's likely he doesn't want any hair down there either.
as for being bare a turn on, i can't answer for it on women but on men it's deffinitly a turn on,
what i've heard from guys is: "skin on skin is hot" with no bush getting in the way
