And you may be right, QXZenith. Most of these ads appear to be for more…ahem, carnal relations. Not quite what I was looking for, but no harm having tried.

And who knows? It might work out great.

And if you don’t try, you’ll never know how if something might’ve worked out.

I think a lot of Zenith’s advice is sound. The letter is just a tad long for an introductory ad. I know you use exactly as many words as you think is nessecary, but perhaps condense it just a little bit. Not saying you should stifle your intellect, obviously! You’re looking for your intellectual equal here. Still your first two paragraphs are by far the best and… well, refer to Zenith he puts it far better than I would.

Go get em’ Adam!

Well, you asked for feedback– I hope you won’t be offended by me giving you my honest opinion.
First of all, while it may be known for the quickest response, Craigslist is not the best place to search for a female companion.

That said, your first two paragraphs (minus the last two sentences of the second– I’ll get there) are incredibly sweet. Speaking as a woman myself, I’m certainly charmed.
However.
First of all, while your commitment to honesty is commendable, it’s not a good idea to bring up your current issues in this first ad, if this is how you go about seeking a friend. It’s not deceitful to wait until your first meeting to bring it up, in the natural flow of conversation; more people will be turned off by the strangeness of bringing it up here at all than would be by the issues themselves.

Likewise, your third paragraph is best left out entirely, or greatly rewritten. Like I said before, there’s no need to talk yourself down in this first letter. But more than that, talking about your build/strength and temper is very… off-putting. The way you phrase it makes people uncomfortable, and I feel you’re giving too much information at once.

And the last two sentences of your fourth paragraph are also a little discomforting; the penultimate line sounds rather like a double entendre I have a feeling you didn’t intend. And while I understand you want a swift response, people will be more comfortable meeting you in person after exchanging emails back and forth first, rather than showing up with no prior acquaintance. Perhaps you could give an email address instead of a physical one?

But all this advice was given against my better judgement; really, like I said before, I think you’re going about this the wrong way. If you want to meet women, try just showing up to social events in your community– maybe your friend Sandy can let you know if there’s anything going on? Try speed dating events, or just go to a public place like a mall and try striking up a conversation.
Or, if you’re leery of approaching people first in person, due to the unusual physique you alluded to, try joining an online community. It’s very easy to search for message boards devoted to something you like (especially since you seem to have such a broad scope of experience); you might enjoy chatting online with people who share your interests, and who knows where that may lead?

I apologize for the length of this comment; please think about what I have to say.

Best of luck either way and warm wishes,
Qara-Xuan
