<human>: Can you provide a brief rundown of the text in within 3 sentences?

This didn't happen today, rather a couple of months ago.

I was swimming in the swimming pool with some energy. It was quite some time that I entered a pool or did anything remotely exercise-like. So my leg muscles were pretty worn out. Suddenly, when the lap was about to finish, I got awful cramping in my right thigh, which rendered it unusable. I somehow managed to get to shallow end and stood upright in the water. 

After about a couple of minutes of breathing heavily and bearing the pain, I started to rub my thigh with my right hand (both my hand and thigh were inside water) to relieve the pain somewhat. 

There were a guy a girl to my left, standing upright in the water and talking to each other. They started to look weirdly towards me. I didn't bother, as at that moment they were the least of my problem. I continued rubbing and panting and it did help somewhat. 

After a while, I came out of the panic mode and got my brain function back. And suddenly thought "Woah! what have I done. It must have looked like I was faping." They sure were whispering and laughing while looking towards me. 

I had to act quickly. I took my leg out of the water somewhat and started exaggerated rubbing movements so that they can see my thigh as well. This I thing settled the matter.
<bot>: I got cramps in my thigh, started rubbing it inside the pool while a couple watched and though I was faping.
