I haven't used Tinder but I've watched as my friends use it. The other problem with these dating apps and sites is people like or are merely confused about what they want. For someone to positively answer the question "would you sleep with someone on the first date?" but then put that they want a long-term relationship - these things seem counter to each other, imho. Both sexes need to be able to say it straight out that they just want sex, then there needs to be a filter to remove these people for the LTR dating pool users. Instead it's "if I can have sex, then the LTR can wait til someone else comes along". That being said, there is a question on OKC that asks how long one would wait before having sex (ex, 3-5 dates, etc). They could make this question have much, much more weight.
