Is it normal feeling of long orgasm
So years ago I was paintballing on a very hot summer day. They make you wear a heavy vest and there's lots of running so I was very exhausted, hot and panting heavy. Yesterday I climbed up Koko Head Crater in Hawaii and the heat was unbearable and I was so exhausted and could barely breath on the trek up.
Both times I got the feeling of an intense orgasm that lasted and lasted and didn't subside. No actual cum came out but it sure felt like cumming, for like an hour straight.
Is this normal? I know some people are into choking themselves for pleasure, is this Why?
