AN etiquette - newbie question
I just booked a reservation for the end of December / first week of January at CSS and am counting down the days! I haven't been to Jamaica in over twenty years and can't wait to get back. I'm looking forward to spending time Au Naturel but will admit to being a newbie. I have no hesitations (although my girlfriend does) about going AN but I do wonder what the proper etiquette is if I happen to get "aroused?" Maybe I shouldn't worry about such a thing, but if I'm on the beach with my girlfriend and we're both AN...? I'm assuming it's ok to just cover up with a towel until things get back to normal? Any feedback and advice would be appreciated.
