Nude Beach

Hey guys -Question. I went hiking at Blacks Beach last week (awesome btw as the weather is finally getting warmer in SD) and two young guys were having oral sex and mutual masturbation in the open on their towel - in no way hidden - in the middle of the beach which was not crowded. The question is whether it is ok to stop and watch them. I slowly walked by as did other guys -one of which was stroking - but if they were out in the open anyway - is it rude to stop, sit down and enjoy the show?
 
Haven’t been to any in awhile, but I loved them. Nothin better then sitting ther with my dog big fat cock hanging down my leg and watching all the looks I get. I also have my wife sit there with her legs wide open so everyone gets a clear view of her big meaty pussy lips. It’s really hot. We actually talk about the ones that walk by and get take their eyes away which is most of them. Lots of young ones stare and couples. We even had a group of young girls ask if they could take a pic of my cock. I said yes but it had to be hard. So they watched my wife stroke it to get it hard for the camera.
