no effect start sucking on her pee hole.wrap your lips around it and flutter your tongue across it you will find it akes her feel real good
Totally normal for her to get wet when you do this - that is a sign she's enjoying it and getting excited!! That liquid will not do you any harm at all.
I have been doing this for my wife all of our married life (37 years) and have only experienced pleasure both for her and for me seeing her come. Enjoy it.
