You have asked some very good questions. For purposes of this answer I may hereon refer to spanking under the broad category of bondage, domination and sadomasochism (BDSM).
Human sexuality is very complicated and poorly understood. Though it is considered taboo in America, spanking and other related BDSM activities are relatively common practices. It is difficult to find precise statistics but generally research shows that approximately 10 percent of the population engages in some form of BDSM-related activities. It is likely higher than 10 percent because of underreporting.
You wonder if cutting may be correlated to your desire to be spanked. It may be. How they would be connected is less clear but it should be investigated. Cutting is unhealthy and it is usually a sign of deep emotional suffering or other problems and often requires psychological help.
The desire to be spanked for sexual arousal is not uncommon. As long as it is not psychologically or physically damaging to the individual, most therapists would not attempt to change this behavior. A therapist should explore whether there is a connection between your desire and the cutting. I cannot answer your specific question since I have limited information.
Because of the cutting I would suggest counseling. If you decide to pursue therapy you may want to consider choosing a therapist who is knowledgeable about BDSM or a sex therapist. Thank you for your question. If you like to find a therapist in your community please search this directory. I wish you the best of luck.
