I would hesitate to over simplify and say that if someone uses a dating app that there is something wrong with them. There is quite a broad variety of dating apps and with it being online a variety of types of people that use them. Some of them are pretty much for hooking up with others and others are more tailored to finding lifelong relationships.

I will agree that in many cases its not ideal as the sole method for finding dates and agree with some of the points you make about being able to sell anything online. While that's true, one needs to be careful with how they approach people and take security very seriously, not believing everyone is what they say they are, but those things considered, I think it can help people to find the right person, just not, in every case.

@TheNightWhistle: you said that the guys that you get intimate too soon "hit it and quit it" and those that you don't let that happen get bored and leave anyway. Seems to me that it's the quality of men you are meeting. Likely the ones that didn't 'get it" from you and left would have been in the same category as the first that would just be gone afterword anyway. Find better men, and take your time actually getting to know them first. Sex will never be a good basis for a lasting relationship.
