Excuse me (us), but I view this from the point that oral sex should really only follow a(n extensive) period of "getting to know you".
Part of this will be
discussion - believe it or not - of (both of) your idiosyncrasies as a
prelude (introduction) to sexual activity.
It seems to me it is a matter of saying (and this is presuming that she has done this before with other chaps) "Hey, I have to tell you something if we are going to do this; it isn't anything really wrong but I have a foreskin that doesn't want to pull back like you would expect but it works
just fine without pulling it back anyway."
However short of "romantic" this might sound, you really
do want to ask her what things she has done in the past (as far as something like sex goes, you have a right to know as does she), and give her a corresponding concept of where
you are at.
And I have two more comments - whether or not your foreskin will pull back and indeed just the same if you were so unfortunate as to have it mutilated - you
do want to arrange to have it clean and sweet-smelling (
not letting soap get into the end; using only water and preferably, a shower to flush water into the opening when you "pout" it as in the picture Jim frequently posts here) if you expect her to put it into her mouth.
The second - "tit for tat" (I rather like that saying). If she is going to do this for you,
generally it is going to be more for your enjoyment than hers. It doesn't have to be of course, she should
only be doing it if she enjoys doing it. So I will
presume that you intend to "go down" on her as well - not necessarily simultaneously (if only because it is difficult to pay proper attention) - so that you might expect her to have a shower as well. Best of all - shower each other in preparation.
