We are going to be visiting Desire Riviera Maya this December and we have some really basic newbie questions. We have really only played a couple of times locally and we're not very experienced in the lifestyle. At the resort we have talked about doing a soft swap, same room, and possibly doing a full swap if we find the right couple. We want to enjoy our trip and ask the really basic questions before we go so we don't embarrass ourselves while we're there:

If we're doing a soft swap only, are condoms expected and/or preferred during oral? If she is giving him a blowjob without a condom, where should he cum? If it's only a soft swap is it expected to show an STI test beforehand? Is an STI test expected before a full swap at the resort?

Sorry for all of the basic questions, but hopefully someone can help!
