If you haven't gotten VIP membership, that's where you'll want to start. Read a lot of reviews. You might also spend some time on your local board, and read the local ladies' posts. They do give you some insight into what the ladies like and dislike.

Sure, my ATF actually prefers oral to penetration.  The fact that she O's three to five times during an appointment bears that out.  I also have a second fav who is nuts for oral as well.

Every lady you meet will not be as into it as you would like. Another thing to remember is that every girl who loves oral doesn't necessarily love it four or five times a day.  Both of the women I mentioned above are UTR and very low volume seeing only one guy a day and sometimes only three or four a week or even in a month.  The chances are if you see a busier gal later in the day or even later in the week your efforts may be appreciated but an extended oral session may just not be in the cards.  Never force it on a gal.  When she starts to move on it means she's had enough.  If you follow her lead you will live to lick another day!

Only if he truly knows what he's doing. Don't get down there and Play in it. LOL
