My wife also bough some "spicy"lubricant, that all her “taiwan girl forum” talk about . That Stimulates both.
We tried and for her felt good…only the sensation but made difficult for reach it…it was longer.
1- Makes more slippery, cons from our perspective.
2- We used in a cabin while camping, no AC, very hot…ajd with that lube… everything was on fire.
3- We clean it up and continue without it.
We used for 10mins, not reach.
After clean it, 15 mins as normally sx she reach 3 and i could feel more and finish.
If keep that thing…maybe i will have a cramp first before reach it
