I have an addiction to nutting in women and not telling them
Do you get kicks from doing that?
Yes, I think it's because I know the girls will hate me for it, but they don't! And I can do something like that and get away with it.
You shouldn't be doing anything sexual without proper consent from the other person. You could end up with an unwanted pregnancy this way.
It's just all about having fun!
What is "fun" for you might not be "fun" for someone else. You need to seek agreement from your partner s if you are going to continue to do these things.
