I'm not sure I understood correctly. Do you mean sweating in the t-shirt while you wear it and wringing the sweat out, or getting it wet with cold water? If you mean the latter, I'll try that.
I keep my fan on 24/7 in the summer, and it's always pointed at me wherever I am, but I always sleep with the fan blowing on me, no matter what time of the year it is. It helps me sleep without getting too hot and sweaty, which happens easily during any season for some reason. Plus, the noise of it helps me sleep. It's hard to explain, but I like the "ambiance", if that makes any sense.
I rarely get sunburned so I've never needed sunscreen, but I'll keep that in mind. My skin is usually pretty moist anyway just by glistening with sweat.
LOL...swamp ass!

Good slang. Yeah, I agree, it always feels nicer when you take a shower afterwards. It's part of my normal shitting routine in the summer.
