I did actually get the 69 to work with one person, but other than her, yes it is highly overrated.

Some women DO like to get mouthfucked...and some absolutely don't. But I think they need to communicate that or at least hint at it. I default to passive instead of active fellatio, but some girls really want the man to take charge that way. "Just use me" or the like will suffice. ONCE trust is established of course
