This is the first foray into an online dating service? Go ahead and sign up for a few of them (okcupid, plentyoffish, zoosk) because the whole point of online dating is querying as large a group as possible for what you are looking for. I guess I'd look at it as a sort of experiment and practice. You are going to have to fill out a bunch of forms asking you about you, your life, what you are looking for, etc, so it'll give you a chance to hone your message in a context where it matters zilch, so nothing to less. If you aren't totally hating it after a bit, then go ahead and plunk down the cash for a membership with one that costs.
Tangent: my esteemed colleague Mr. Falcon is correct about Tinder. If Tinder is a place just for shady hookups to transmit venereal disease, then Twitter is just a place for people to liveblog their poops. Put another way, their cheap characterization of these services is complete BS, and it's often a result of having minimal/zero actual experience with them...so they repeat what they hear like silly parrots. Disregard their nonsense, they don't even know they are dumb.
Personally, I suck at the digital services, and I've tried them all out. But, it was worth doing because I learned that these sorts of sites aren't really for me...I can't go out and "intend" to try and date, and come up with anything resembling success. The only good things I've found over the years are relationships that just sort of fall into my lap, and I jump on the opportunity. I guess that's a bit of a passive approach to dating, but I'm happy with it. I also really loathe filling out those stupid questionnaire forms asking me what my ideal first date is. Hate them. I also clearly suck at them. Even had a female friend write mine for me. I took a look at it and my stomach curled. The "put on a big happy face and pretend that life is absolutely perfect" dog-and-pony show is off-putting to me...but it's expected one act like that, even though its a fact that the reality of life not being perfect is going to inevitably come around. Cleaning oneself up to be presentable in public is one thing, a lack of authenticity is another. I can tell that going to start rambling along this line of thought so I'm going to stop.
Moving right along, my own anecdote aside, hundreds of thousands of people, if not millions, get something real out of the effort, and it would frankly be dumb to not give online dating a chance. If finding a partner is a priority in your life (and it usually is in everyone's life), then due diligence sort of demands one look under that rock to see whats there.
TL;DR: The low-down is that you should go for it so you can experience it for yourself, a ton of people find really good relationships because they took the chance on online dating, so its at least worth a try. Use a burner email of course, and, if possible, a burner phone number if ya got one. Set them to auto-forward to your real accounts, and try not to end up in a bathtub full of ice and missing a kidney.
Have fun out there
