I mentioned a safe word to him and he thinks using words not related to sex is weird.He doesn't spank me or whip me much at all.He says he has to think about it,he doesn't like to do it really but does it sometimes because he knows I like it.I made a suggestion for me to move away a little when it does start to hurt more then I like it too though.I rarely ever have to move away from him,wish I did.Thank you for advise, I really appreciate it.
