When a woman has an orgasm she does release fluids. It is a mental but also a physiological thing.
Ex: she can really like it but their has to be stimulation in the clit area or the g spot.
And also their can be a lot of action in the g spot or clit area and if she is not into it then she will never climax
if you never had one or your partner ( you never specified a sex, you just said you were on a friends account), it will be an amazing feeling, almost and addicting feeling.
