I've been with allsorts.
Some who where easily and multiply orgasmic whatever i did, some who where 'reasonably' orgasmic (like, the middle single figures mentioned, max), some who can only come in one or two ways (with their hand or my tongue/hand, for example), some who could never orgasm with another person in the room (to the extent of kicking me out of the room after i finished up, heh) and some who just couldn't at all.
Squirters, le petit mort practitioners, screamers, whimperers, silentists, pray-ers, cursers, hitters and literal lip biters (i saw this particular lass draw her own blood one time i kept her on the edge for an extended period - not big or clever).
The orgasmititude, or sensitivity of a lady is a varied and special as the rest of her physical and mental aspects. Treat it like that.
Pressure is the last thing a woman should feel or have foisted on her. 'Normally' the ladies who have had troubles with their orgasm, we've found they have particular, peculiar sensitivities in other dimensions. Extremely sensitive nipples, anal sex can drive them crazy, licking the back of their knee can do similar...
Orgasm isn't everything, don't get me wrong, it's great and all, but even as a bloke there are times it just ain't gonna happen for me... and sometimes i can't stop it!

Counting orgasms? Like counting lovers. It's a silly idea, and very retentive.
ok, enough rambling. I tired now.
