Yes, because he is large and I am small. I'm also very sensitive, so I'm very picky about lubes. I like Sliquid Organics (Gel & Silk) as well as Aqua Sensitive. Sliquid Silk is a hybrid water/silicone lube, so it's better for longer sessions. The other two are water-based, so cleanup is easy but they dry faster. Aqua Sensitive is very thin and runny, and Sliquid Organics Gel is thicker & with more cushion.

Not during vaginal sex, but we use lube for anal sex. I prefer a silicone based lubricant for anal since we usually do that in the shower. We like the Jack Aide Silicone lube for that.

We don't usually use lube. Sometimes we will use flavored lube for oral sex to spice things up.

I always use lube. I mostly use Colt. I think it is a good lube and I can use it with my toys as well.

Sometimes; it depends on how much time we have for foreplay. We pretty much always use Maximus. When I peg my boyfriend, he prefers Wet Platinum.

Yes, probe silky light.

Generally, no. We do sometimes add lube if we're being particularly rough, but otherwise we don't bother.
