I use lube for PIV if it is going to be going on for any extended period of time (even if I start out well-lubed PIV tends to "use up" what I make) - I like the warming stuff and the His/Hers sets. BUT if there is any chance we will be switching it up later I prefer this cheap Kiwi-Strawberry stuff I picked up at Wally-World...tastes better (on his lips OR his penis).
None of us has any reactions to anything (or condom issues to consider) but it is good to know alternatives In Case of Emergency (i.e. empty lube bottle).
