.... Would still love to chat with bulls/couples about this life and some things I can do to push this along slowly without being overly aggressive about it.
She's probably not comfortable with it because your lady just has her priorities in line; possibly, her first priority is to confirm the relationship she has with you. Either she wants to be sure that you're the right choice for her,
long term, or she just wishes not to do anything that might change the relationship she has with you, now. Trust me ... allowing another man to fuck your woman
will change your relationship you currently have with her. Where do you see your relationship with her going? ... do you consider her a long term relationship? If so, have you told her that?
You notice many couples are in their 30's, or after, before they start exploring & involving others in their sexual relationship. That's often caused by predictably routine, boredom sex after being together 5 or 10 years. Also, you're not only wanting her to consider having sex with another man, but another man of a different race ... two very distinct, but different, goals. Have you ever had a 3-some with her, involving another man? If you've never tried "swinging", its good to establish good parameters to it before starting it up.
The fact that she so calmly discusses your sexual fantasy is a big +plus; the ability to be able to discuss sensitive issues is a good sign, actually. I think you are lucky to have such a devoted lady. If you push the issue, she could percieve your motives as selfishness, or as a sign of deteriorating interest in her, and neither of those would help youwith your fantasy goals. Good luck ... Mac
