Is lust at first sight normal...for a woman?

I've done my share of undressing guys with my eyes; teasing, n finally, giving into temptation. ANd yes, there was love there, but the first sight reaction was lust, because I didn't know what was there to love...but the dreams I had the night after I saw those men would b purely lustful. I know guys have these fantasies quite a bit. I mean, that's what is right? But is it normal, or even ok for a lady to have such thoughts? I mean, no romance, no wooing, just plain,(maybe a drink or two), then totally a one-nighter dream(or experience? With my ex, I held off til marriage...n was PROUD of myself!!!!!!! Normally I wouldn't b in matters of chastity, because saying no either came easy, or I didn't really have opportunities where the n word could b used. But with my ex, no, meant no, n I would've given myself a hug n taken myself out for a drink for such a feat(if i had some outta body experience). From the moment I saw him, steamy ex ran through my mind all the time. Just curious to also see if guy's n girl's minds actually are wired similarly, though not the same. thanks for answering.
