If it makes you feel any better, I recently tried online dating for the first time, and LOTS of people on there are just looking for something casual (or sexual) and/or are going on tons and tons of dates to try and find someone they like. I was kind of surprised to discover this, but it turns out that the culture of online dating is totally different from the culture of regular dating--agreeing to go on a date doesn't mean that you're Interested in the person, it just means that you are sufficiently interested to want to meet them in person. No commitment implied, at all.

(I dunno if it matters, but I was in the US and using Bumble and Coffee Meets Bagel.)
