Don't just rush it
Men browse through these apps during bedtime or late at night and women may not be naturally ready to respond immediately. Repeated pinging may make you look overeager as well as creepy. Be patient enough!
Avoid awkward questions
Rather than asking something 'how much weight have you lost?' after looking at several pictures the woman used for her profile, try to build a comfortable rapport.
Don't be a Clown!
It is quite natural that men really love to make women laugh. Make sure that they laugh with you, and not at you. Rather than introducing yourself with only a oneliner which is over confident, simply start trying with a 'hello' or 'hi'!
Don't Talk About Common Friends
Sometimes you may notice some common friends showing up on your profile. Do not talk about them until you have planned properly to meet each other.
Beating around the bush, stop it!
You need to be honest at some point soon over what exactly you are looking for, whether it is for a date or a hook-up.
Asking number too soon, no way!
The chat line on quite a few dating apps is slow. But there may not be a silly thing like asking for a number very soon.
