I've experienced the same thing kinda over the last couple of years since I've been using Sniffies, which has been a lot more than Grindr and other apps / sites over the last several years. I live in an apartment complex and am seeing several guys just in my complex alone pop up - from none at all to maybe 5 or 6 guys, not to mention the increases from all the other complexes and residences in my local area. I kinda wonder if the app itself is becoming more popular or if more guys are getting comfortable venturing out for man-on-man sex. I do seem to encounter more "straight" labeled guys looking for just head or telling me they want a cum-and-go fuck scenario.
I have to say across most of the apps I encounter guys who prefer to travel though... I'm almost always hosting or proposing car or motel alternatives.
