I certainly can appreciate what you are saying. However, as someone who used to make cases against people in the legal system, just not using the word would not free you from liability. A case is crafted from all the circumstances and checking that you are "into" anal, oral, toys, etc. and that you offer "activities in the bedroom" make it hard to explain why you are not in fact a sex companion, no matter what words you may use. Also clients are going to ask you for that info somewhere down the road if that is what they are interested in and you are going to have to give the authorities that info. So, yes, for sure it is harder but in no way impossible.
