@helenS And other times, replying allows the person to send an inappropriate photo. They can’t send those unless you reply to that first DM. Sadly, it’s those fellows who make folk less willing to take a chance.
@helenS I have, alas. Didn’t like it. Admittedly it doesn’t bother everyone. But I suspect the OP would probably rather not receive them. Being careful with dms isn’t a bad idea.
@Funtoy4u People do stupid things occasionally and I am certainly no exception. If I were a man I don't think I'd ever send a nude picture to a woman because you can never predict how she will react.
