well, I never realized it at the time we were dating, but I had one gf tell me after we broke up that she missed my big cock.
I dated/fucked another gal when her fiancee was out of town. after awhile, it went from sex to love, at least for her. she told me she first loved the sex... my thick, big cock and then she fell in love with the rest of me, would daydream about me and things we do in & out of bed. she wanted a commitment from me, and I asked her to drop her committment to the other guy. she balked at that. we stopped seeing each other. I got a new gf, and she found out. she came looking for me one night, needing a big cock, and ran into me and new gf. super pissed. anyway, a couple mos later, I looked her up to straighten things out, she was still pissed at me. but when I turned to leave, she grabbed my arm, turned be back around, grabbed my crotch and said, "i'm still mad at you, but I still need your dick." so we spent the nite fucking, and I never saw her again after that.
