Its not something I have to do. I will do it if the lady asks. The reason that some women like it and turns them on it makes them feel like a dirty girl and some girls like feeling like a slut in the bedroom. Same reason why some like to have their hairs pulled back or feel used.
As stated in another thread similar to this I prefer CIAO. (Come in any orface). Nothing like the feeling of mouth, pussy, or ass holes warmth milking your cock for every drop as you shudder as you let it out.
