Talking to women I am not interested in

There are a couple of women who seem interested in me. One from religion, and she is actually attractive, but I am not interested in her because she is a couple of years older than me. One from work, but I am not interested in her because she is a couple of years older than me, plus she is ugly. Neither is American, one is Iranian and one is Indian.

I am thinking I should really make an effort to talk to these women, just for the sake of becoming comfortable around women. The issue is how do I do this while keeping distance and not offending anyone? This is an issue for the first woman especially, because she seems like a nice decent woman who I am connected to religiously and I wouldn't want to lead her on, out of respect for her. I have actually been avoiding her out of fear that I will end up rejecting her and offending her. I will see her at a religious gathering Sunday, so maybe I will drink some alcohol first, and I will keep my cool and things will naturally fall into place. My social intuition seems heightened on alcohol.

Why are you overthinking and over analyzing all these basic human interactions? You are a 32 year old man!
