I have no such problems. Perhaps it is youthful lubricity, hedge trimming, my type of jewelry or frequency of sexual activity, but genital shifting and sticking has never been an issue. I suggest the above? Buttering is great, esp. with garlic.

Seriously, though, I just use a little at the thigh/softparts intersection... don't need it much elsewhere. Long rides, sorry, jewelry comes out. Re: the infection bit, I'd stay the EFF away from petroleum based anything, oils, etc. great for trapping moisture. shower well, don't soap, and if it's bad, use monistat or the like creme, maybe w/ a little vinegar and/ or tea tree oil to lower the ph and act as natural fungicides. uhh... careful with the TT oil. *shiver* it's... uh... well... you'll get it.
