Funny! For myself I usually ask what do you not like? In my mind they already say what they like on the page if I see anything missing that I like then I would ask them specifically. If they ask me I usually say I am up for anything just nothing too extreme like blood,scat, sounding, raw, drugs, or cbt. It is just easier and faster to narrow down what someone does not like than what they do like. Plus then you dont feel awkward and give confused looks when you hear things like dont suck my nipples or I dont like to get fingered.
If I was going to ask if they liked something I would most likely word it as, "Would you like me to prepare anything beforehand." In my mind I was thinking of thing like manscape or wear a jockstrap or fill up your bladder. However what I 99%got was in not the exact same words were...
lmao
