what you did was absolutly right. as an actor in a haunt, the rule for both us
and customers is "they dont touch us, we dont touch them". it is normal for someone to accidentally brush up against someone or maybe even bump into
them, but for someone to touch you on purpous and especially on a sensitive
area, you were right for doing this.
you shouldnt feel afraid or embarrased. your job is to act, and for someone to
disrupt you during is wrong and should be removed, as they an cause others or themselves harm.
First year acting for me was really crazy. I had never done anything like it before, so i wasnt sure what exactly to do. thankfully i had some people teach me some movements and techniques that caused great startles. i actually met my good friends at local haunt, and i still keep in touch with the others. the haunt "family" as its called are a rare and unique bunch of people, and are the most laid back and awesome people you will find.
when dealing with negative guests, its usually best to perform your scare, and then move back to your spot or reset your scene. this way you have less a chance in dealing with someone. you have to learn to let words slide off your shoulder, and not take things personally. some people are just wanting to piss others off, so i dont encourage them by saying anything back other than script or whatever i feel is necesarry.
there may be a time or two that you will have to deal with a customer under the influence of alcohol, and its your houses duty to weed these guys out from entering. with all their effort though, its possible for one to slip in. the biggest thing you will need to learn is your hearing. listen for everything that goes on around you, as they are your cueing, and from hearing the response of the crowd, you can tell how they are going to act. at any moment if you feel unsafe or uncomfortable, let someone know and try to figure out a way for you to feel more secure.
hopefully i gave you some words to help you during your first year, and do not be afraid to message anyone on this message board. we all want to help each other out and hope that everyones house goes successfully :-D
