I'm 35, so I will mention the things that stood out to me most as serious red flags for a 38-year-old's profile:

• You're obviously a nerd. Embrace it. Saying all the nerdy things you like but then saying you dot like being called a nerd makes you seem incredibly insecure. You're at the stage of life where you shouldn't give a damn what other people think.

• You feel the need to mention more than once how you don't like "mainstream" stuff. I'm pretty sure you're too old to be a hipster. I like some "mainstream" stuff - what I don't like is judgmental people who think their taste is automatically superior because it's more obscure.

• You don't mention what you do for work. If you're a 38-year-old focusing on going back to college for a career change, put that. Just know that a lot of women don't want to date a 38-year-old who is still "finding himself." Most of us know who and what we are by this point.

• You've listed that you will date as young as 18. That's enough for an automatic pass for me, because there's so little life experience in common a relationship is impossible, which to me indicates you're only interested in casual sex, regardless of what you put what you're looking for.

• You put that you're looking for new friends or short-term dating. To me, that's not a guy who is serious about finding someone to date long-term. Most guys who are looking for a relationship are very clear about it. Looking for "new friends" and "short-term dating" are so rare on profiles of guys above 35 that it makes me think it's code for casual sex when you don't want to put casual sex down as an option because you know a lot of women won't go for it.
