Breed & Seed... Ugh!

So... I was just looking through the craigslist men seeking men ads...
Hey! Don't judge.
Stop here, as this post may be overly graphic adult...
I get the desire to fuck without a condom. It feels great. It's so in the now. Of course people get tempted...
I'm not going to enter a lecture mode about safe sex... I've given in to the dark side on occasion, & guiltily took the test afterward. I'm not able to claim innocence. It's not in my nature to deny my transgressions anyway.
I'm an over-sharer... Hence, this post...
What has me just shuddering with revulsion, is the title of this post. I've seen it in quite a few posts tonight...
This mentality of being used... The guys who write that in an ad... Breed me & seed me...
They offer (I'll assume they are picky-ish) to be bent over & waiting for the guy coming over. 'Fuck me & go.'
Now... Sex is just sex. I separate sex from making love. There is a distinction to be made.
Yet... This is less...
I just fail to understand placing no self-worth in what you bring to it. To give of yourself so freely that it has absolutely no meaning...
Is that ultruism, or is it shame?
