Are you also fearful of kissing?

If we don't succeed, we run the risk of failure.

The jellyfish position is not the subject of this discussion. It's your
introduction.

The you're not floating face down, are you?

I certainly don't go around kissing those I don't know. Do you?

A snorkel is a good start if you are planning to bring your own
equipment, followed closely by a mask. You can usually borrow
fins if you're trying to travel light.

One consideration about the prescription mask, is to use disposable
contact lenses instead. (That is, if you can wear contacts). They
have the advantage of not being a serious loss if you lose them, and
you can also see your way around the dive boat, or on the surface of
the water, without your mask on (which otherwise could get steamed up).
