Now as far as the oral sex thing, people come to the club with the set of skills, techniques and preferences that they have and should not be focused on what they aren't into.
When you make your first trip to a club you should set your sights on meeting some new people, mingling on a social level while enjoying the sexual energy that can come from an environment like a club. Do some dancing, maybe some flirting and just getting acquianted with some people and just see where the attraction and chemistry takes you. The chances are the first time you are there you will not meet anyone that she would even want to hold hands with let alone give a blow job or get "pounded" anyway.
Focus on interacting with people and getting tuned in to the level of attraction and chemistry you feel with them and go where that takes you as opposed to focussing on specific sex acts. When you meet someone and there is an attraction and chemistry let that flow to what ever level it takes you. With some people it will just be "hello" followed soon by "nice to meet you, have a nice evening." Other people it may involve some flirting or dancing. some people may involve some smooching or even making out and some people even up to "pounding."
Do not introduce yourself by saying "hi my name is ______ and I don't do oral." Just go with the flow and let the chemistry take you to where ever it takes you. do what you want to do as long as it is consensual and don't do what you don't want to do. It really is as simple as that.
Will there be people that reject you for not blowing them? Absolutely. Just as there will be people that will reject you because you hair is too long while others will because your hair is too short. Some will reject you cause you are too tall and too skinny while others will because you are too short and fat. I could go on and on but you get my point.
Swinging is a game of a thousand rejections but it is sure a lot of fun when the stars line up and things work out
