I have had feelings for other women before. I had a good friend...and we used to snuggle up on the couch and watch movies together. I knew she was bisexual...and I liked it.
There's another woman in my life, a friend of mine, that I have felt attraction to as well (though I know she's very much heterosexual and very happily married) -- but there have definitely been other women I have been attracted...the attraction to my T is just a lot stronger.
