Can you tell me what is your weird kink?
What drove you to have a kink?
My childhood is the only reason why I am who I am now.
While asking about someone's kinks can be a very private and sensitive subject, it's okay to do so as long as everyone is comfortable in the conversation. It's good to be open and honest about sexual matters as being too closed and repressed can lead to psychological issues.
My partner doesn't know.
It would be good to open up to your partner about any kinks that you have. This may help you to be more intimate with your partner.
