I tend to shower once a day, cept on weekends if I'm doing nothing I might go a day without showering...of course, on the rare occasions that I go camping, I can't shower for 1-3 days, but that's alright. I don't tend to stink much naturally...I've heard vegitarians don't stink much, but I'm only mostly vegitarian. ^_^ The only time my sweat stinks anyway is if I spend all day playing videogames or watching TV, if I actually work out, my sweat smells...well, almost sweet. I haven't figured that out...
...maybe it's just cause I'm such a sweetie/nice/sweet guy... ^_^;
On rare occasions, I'll shower twice in a day if I get really sweaty and it feels sticky and icky, or if I go swiming in either a lake or a choline pool, the former which can tend to feel icky (though not always) and the latter always feels sticky and dries my skin, which sucks. But the most I'll shower in a day is, realistically, twice, only three times if it's REALLY waranted. I think the most I've ever showered/bathed in a day is three times, four at the most, but I don't ever remember doing it four times...
...of course, I actually like long (10-40 minute, depending) warm showers, but I only like doing it once a day. What can I say, a warm shower is relaxing and I like getting REALLY clean (and no, I don't do THAT when I shower anymore...though that was what I did when I was a teen, so maybe that's what started it...), so I tend to take longer showers, but I don't like doing it much...I know, kinda a counter thing; I like showers when I'm showering, but when I'm not I don't really wanna do it. I'm just weird like that.
