(((Hugs))). Sounds like a very awkward and confusing situation. Your feelings of arousal are not shameful. They are just feelings. It sounds like she is a good looking woman, whom to you is practically a stranger. I think most people would be physically excited by an attractive stranger flirting with them. Your rational mind knows that it is wrong, which...well anyone who has ever browsed a porn site knows that this is not a terribly uncommon taboo fantasy. But IRL it is incest. Your mother is being terribly in appropriate, however. This woman carried you for 9+ mnths and gave birth to you! Obviously, she is sexually frustrated being in prison for that long, but that is no excuse for her behavior towards you. She is a sick lady. I think it would be best to talk to a trained professional to get advice on how to set firm clear boundaries with her and how best to approach her with them. If she is not able to respect your boundaries or gets irate at the Meer thought that she is behaving at all inappropriately.. then it is probably in your best interest to cut ties with her all together. She has been absent most of your life and what you actually need from her is A MOTHER! If you want to explore your maternal sexually desires, by all means watch some milf porn, and join one of the many online casual hook up sites. You are a young virile 28 yr old man.. be specific about what you are looking for and I'm sure you will have more cougars than you know what do do with vying for your attention! be safe and I hope everything works out for you..... But whatever you do...DO NOT HAVE SEX W/ YOUR MOTHER!!
