Hi. I suspect you'd get better exposure if this was in Better Profiles, but I'll do what I can. And blunt is my default, so you're in luck.
First, I like your face, but I'm kinda torn about the goofy expressions and the backwards hat thing. Also, in one photo it looks like you have a lazy eye. It's fine if you do, but if you don't, you might want to switch to one where both eyes are looking in the same direction.
I also really like your certs. They did you proud. Your tagline is fine, but it's man rather than male. SLS's grammar is shit, but yours needn't be. You might, for some really subtle reasons, consider changing your age range to 25 to 55. You won't discourage a single 18-24 year old by doing so and you'll make a better impression on women 35 and up.
In Looking For, you have some sloppy typos, which tells me you didn't use spell check. Do that religiously, on your profile and in your emails. So, it's I'm not Im or im. And what you have is okay, although the last line belongs elsewhere, but you need to talk more about who you're looking for, because that's the purpose of this section. A man looking for women doesn't really need any explanation, but you're also open to couples, so talk about looking for women and couples in a way that signals your equal interest in both.
Description is okay. It will certainly make for some conversation. Can you say a little more about yourself in the same vein? If you can't, I think what you have is fine, but it feels like it could be just a hair more intriguing.
What's in Additional comments belongs in Fantasies and that leaves you with a different empty section (never leave an empty section). You can repurpose that surplus line in Looking For here.
Anyway, collect any suggestions you get, make the changes and get them approved and then, after you fix your smoking and drinking toggles (it's the gift SLS gives anyone who makes a change to their profiles), come back for a review, either here or in a new thread in Better Profiles.
Good luck.
