It's a hit and miss, sometimes you meet a really horny and honest guy who enjoys spending some time with you, sometimes just a stupid, nasty little faker who is only intersted in your money and wants more, more, more...
The problem is, that both can be really sweet and sexy at the start! :-)
Don't forget to lock up your valuables when receiving a guy in your flat. My mobile phone was stolen twice. My mistake because of the lack of experience I guess.

But working with the apps like romeo of grindr is even more difficult to jugde if you have the right guy.
At least when you meet someone and have a coffee together you can have a better judgement.
Just walk and see what happens...
