How Do Guys Work At Waterparks And Not Get Hard?

We went to a waterpark this past weekend, nothing but young women in thongs and less, not even joking around. I saw pussy lips in pulled up suit bottoms, nipple slips were like a regular thing, women would pull their suits out adjusting them and I would see full breast or ass cheeks. There was a woman on the lazy river that had a bikini on that was too small, her breasts were spilling out both sides of the cups and the bottoms were no where to be seen from the rear when she stood up at the end. She bent over picking up her tube and I swear I saw the ring around her anus.
when I was younger everyone wore t-shirts and shorts to these places, I would see a few bikinis but not that small, full coverage ones and never any thongs. I am not complaining at all, been thinking about a retirement gig working at one for sure. The only problem is I will have to where a jock strap to keep my erection hidden.
