I enjoy playing in water, playing with fire, playing with clay, playing with Legos, and playing around with my wife.
Does this mean I simply
must be autistic?

I'm pretty darn sure that's not quite what the OP meant.
There's a difference between "hey I drink water, ZOMG!! ! I like swimming too!" and "Hey I have this seriously obsessive view of water and will absolutely gravitate towards it in any conceivable situation even if it doesnt make any sense whatsoever".
Me and showers, for example. Lots of people enjoy a good hot shower. But for me, that's not good enough. I turn it up to maximum heat and let it sit like that for 10 minutes before I go back into the bathroom. Why? Because it DRENCHES EVERYTHING. Everything in the bathroom is soaked and covered in water. It'll drip from the ceiling. It covers the area around the sink. It covers EVERYTHING. And the steam is typically very thick. I dont turn the fan on, because it'd drain the steam, cant have that, it'd lower the presence of water in the room. Even if I'm not taking a shower but am in the bathroom for whatever other reason, I'll still turn the shower on and have it do that because water. I do this at hotels as well. Have to. It bothers me too much if I dont.
Speaking of hotels, there's the hotel pools. Even if I dont actually go swim in them... which I cant do if my back is acting up, or something like that (argh), the mere existence of one and the knowledge that it is nearby is comforting. Because the presence of water is comforting. Why? Heck if I know. Everyone I know thinks this bit (and the various other ways it applies for me) is pretty damn weird. Granted, they usually think that about me in general, but that one apparently is stranger than most other things. A chlorine scent in the air is also comforting, because I associate it with the pools.
And then there's the ocean. If I can actually get INTO the water there, it's absolute freaking ecstasy. Everything else ceases to matter whatsoever when this happens. I dont even need to swim or... DO anything at all. I'll happily just stand in it for 3 hours. This, too, apparently is very strange. Not that I care, it's the freaking ocean, everyone else can just go jump off a cliff, really. There was one time when on a trip down in.... somewhere.... Cayman Islands if I recall... where this one attraction is a specific area called Stingray City. You get on this boat, you go out to this spot, where the water is about 4.5 feet deep if I recall, and you play with the large population of stingrays that for whatever reason congregate at that spot, and yes "play with the stingrays" is a bloody strange idea, what with the bit where they're STINGrays, but that's exactly what you do when there. For everyone else, it's like, "Whoa, cool, stingrays!" For me, it was "HOLY #(%A& OCEAN!!!111" and the stingrays were just an added bonus.
I could keep rambling on about things related to water for quite some time, but I'll stop there lest I seem even more strange than usual. Wether or not this has anything to do with the autism specifically, I have no clue. Doesnt really matter, in the end; it is what it is.
