I have a "friend" who's in a LTR. His 8-month gf:

-Initiates sex quite often
-Has an IUD and lets him raw-dog it
-Occasionally is down for anal
-Usually climaxes from coitus, but has told him when she did and when she didn't
-Buys him things, doesn't ask for money or incur much expense, cleans his house without asking, is generally a doll

BUT:

-After sex, she consistently sprints to the bathroom like an escaped felon, to wipe his load out of her junk

What does this indicate, if anything?
