Is it normal 2 <3your mom?

Is it normal to be highly attracted to your mom? I am adopted but I am only two years younger than my mom. She is single and I am very attracted to her. I try to impress her with my shirt off and she smiles. Sometimes it's really akward because we live in a small condo with one bed and a couch. I usually sleep with her and I love it. I sleep in just boxers and I sometimes wanna rip them off and have sex with her. I don't think of her as my mom. I told her about my feelings and she said it was okay because she sometimes felt like that. We sometimes have romantic dinners with wine and dim lights and we have made out before. I wanna have sex with her so I might ask her. Should I? She is somewhat attracted to me so I don't know if she'll say yes. What should I do?
