Ive been with my girlfriend for 3 years now and we have tested the BDSM waters a few times now. Well this time I think it may stick seeing as Ill soon be out of college and Im going to pop the question....you know...Marriage...rings and everything. Well with our BDSM and her needing control frequently, how do I have a healthy relationship with my soon to be wire, and control her the way she needs and craves? Little help?
