LOL, I like that guy. However, some of that information is stuff I already knew about. It's why I'm having better results going out than grindr/jack'd anyway. People make up all sorts of impressions by photos.
The only thing I'd say is I haven't found having normal dressed photos to make any difference in the types of guys I've met versus something shirtless. It just got me less responses. These phone apps and dating sites lend themselves to serial daters, experimentalists and guys who play on the side. Can't tell you how many I've met like that. Shit, I have to wean em out in my area simply because of race. Most these guys have no intention period of getting into something serious with a Black man. They just testing out the waters, on some experimental bullshit. Or, they bored of the one they with and always on the lookout for the next one that pops up. This place is fucking whacked the fuck out.
On the flip side, I've tend to notice guys who wear tank tops everytime you see them out, are usually not to be taken seriously. Like dude, do you ever wear something besides a tank top? It's Saturday night.
