This is when you exchange numbers via the app in order to communicate more effectively about the IRL date you're trying to arrange. If you are talking time and place, offer up your number. Overall, Golden recommends waiting to share your number once a date, time, and location are confirmed.
If someone you are interested in is messaging you on Tinder and asks for your number, go ahead and online dating give cell number it to them. You don't have to withhold your number because it might lead to becoming "text buddies.
In terms of asking for a match's number? I couldn't stop thinking about how cute and funny he was, so I shot him my number.
The good news is you don't actually have to give out your personal phone number to an online match. Lots of apps out there will provide you.
