Yeah, I don't even bother reading Wikipedia. I have found far too many errors in it to trust it now.
Yeah, I don't know too much about this either. I heard a long time ago, that women who get in the mood with no release may be more prone to infections or something, but I can't remember where I even heard that and if it was a reliable source. I checked the internet and did not find anything.
My guess would be that not having a sexual release won't hurt you in any way. After all, it is not at all uncommon for women to not masturbate, or have sex, or orgasm, or even all three.
I also have no idea what fluid wikipedia was talking about. When women orgasm, we usually don't release any fluids other than some lubrication, and that comes from the walls of the vagina, not the ovaries. (I am actually talking to a doctor friend of mine on YIM as I type this, so this is coming from me and a doctor

).
I would suggest asking your ob-gyn more about it the next time you go in just to be on the safe side, but I don't think you're doing yourself any harm by not having a release.
