I would suggest not posting it on your profile, but being honest once you start chatting with them. In your profile, lead with your hobbies and interests and a little about your personality, and keep it fun and conversational. You would not believe how many guys come across as bitter, resentful, deeply unconfident, or having other major emotional issues, right there in their dating profile. I think it comes from a combination of trying to be clever and stand out, plus some serious issues with women. And they seem to have no idea why they’re not getting dates, or blame it on some outside factor like women being shallow bitches. Ugh! Ok, that’s enough of that tangent.
Here’s my thought process, as a woman looking at a guy’s profile. If a guy’s profile has an unhappy tone, the girl will imagine a future relationship where she is constantly having to bolster his self-esteem or otherwise reassure him. Related, it’s important for a guy to have interests outside the relationship. You don’t have to be a social butterfly or run triatholons or anything, but being engaged and involved in something is important, you know?
An important thing to consider is that meeting a guy from online can be a potential safety hazard for women. When I’ve gone online dating, I always used a buddy system and left the guy’s name and our plans written out next to my computer. I’m not saying that to put you off online dating, just to help you see things from our side of the fence. One of the earliest red flags is a profile with an unhappy or angry tone, or any kind of sexual content. (It’s too early!)
So anyway, I think you should write about the things that make you happy and why you enjoy them. You’re thoughtful and have a good sense of humor, and you’ve made a lot of interesting and inquisitive questions on here. Once you meet a lady and talk to her for a bit, you should bring it up then. Be straightforward, but don’t dwell on it. One of the most important parts of the getting to know you stage of dating is learning about each other’s unique personalities (and lives.)
Anyway, I’d be totally happy to look over your profile if you’d like. Good luck!
