I don't use them in live shows hardly ever. I'll use the dong, but not the cum lube. For customs, I add an extra $99, but of that, I get $60. Even then I rarely accept a custom w that in it. Because that's still too cheap to be fucking with that stuff on all my towels, floor etc. I might reconsider that policy in the future, now I have wooden floors, but methinks not. In general, customs are already a huge money loss for me 95% of the time.
Remember a lot of them want it shot in your face. There goes fucking makeup and hair if you don't mind my French. An hour lost right there. I like to wear false lashes too, and those take forever to reapply and are not the cheapest. I'm really not into cum lube for live shows at all. Keep in mind I am a Streamate only model, who mostly does exclusive shows back to back.
