"I knew I loved Lynn and I hoped she felt the same way about me. I had never fallen so hard for a woman, nor had I ever lasted as long with one. Most women decided I was trouble and gave me walking papers before things got serious. Getting rejected did hurt, but we usually managed to part on friendly terms, which helped take a lot of the sting out of it. Besides, plenty of other women were willing to offer me solace, so I learned to live within the myth that someday I'd find the woman meant for me.
"Now that day had dawned and I found it more terrifying than all the gun battles I'd lived through. In those instances the worst that could happen was that I could die. In this situation, I could end up living. I'd have responsibilities and obligations. While Lynn was more than worth all that, a huge chunk of me saw my window to freedom snapping shut.
"Enter Selene. She and Lynn were of the same species and gender, but the similarities ended there. Selene was very attractive and aggressive. Being persued by someone so powerful and desirable was one hell of an ego-steroid. I was staring ata future imprisoned with one woman, and Selene was handing me a 'Get out of Jail Free' card."
