Sparks, you're probably allergic to latex.
I'd stay away from condoms unless you need them, and then try non-latex ones. They're so expensive, though.
Lube is fabulous IF you have a good one. Most of the ones on the general market, (Astroglide, KY, etc) are grotty and gross and tacky. I MUCH prefer the Revelation that I sell (unintentional shameless plug). It's silky and not tacky and doesn't have a gross taste.
Ditto. It never gets sticky and you can re-wet it for hours on end even though it's water-based. I've tried a ton of different brands/types and, honestly, nothing has even come close yet. Not even Wet, which seems to be the favorite brand for most of the folks in the sex toy shops I've visited.
Suppose it depends where you want to be sticking things... never normally have much of a problem
Ah, but if you do decide to stick things in places with no natural lubrication, you're going to need a good lube. And definitely some condoms. Durex has "her pleasure" berry scented ones, even.
