Here are a few of my rules and they have been bent/broken depending on the woman I'm with.
If she spits no kissing afterwords.
If I go down on her and she kisses me after I will kiss her if she swallows.
You wait 25hrs before going down on her after you shoot inside of her.
The taste of love is sweet, if your in love it shouldn't matter who's jizz it is.
Now I've only been w/ one woman who would swallow every time and I did the same for her, we always kissed after sex, and she was the BEST I've ever had!! My current wife comes in buckets so I need rain gear and a snorkel, it is impossible to swallow it all, I'd drown!! She will swallow once or twice a year if I'm lucky. She will kiss me after I go down on her but she has to be turned on real bad, again once or twice a year.
Sex is fun, sex is good!
