If you’ve been enjoying casual conversation for a few minutes, ask him for his number. The first time you meet may not be the time to ask him out for coffee. If your crush is 0.5 miles away, why not? Who can blame us in a culture where we are so commonly reduced to our basic anatomy? You assume the risk of seeing one (or ten) every time you log onto the app.
However, if you’re on Grindr or Scruff (or any gay sex site, really), seeing unrequested cocks, holes, and sex shots is unavoidable. If they end up on a child’s phone, things get very messy, and you may need to call a lawyer. The trouble with sending nudes is that it’s difficult to control their dissemination once you send them. Sending nudes between two consenting adults is generally fine, although if distributed vengefully, as sometimes happens between exes, you can sue for harassment. Sending XXX pics, solicited or otherwise, is a severe offense in all 50 states if the sender or receiver is underage - even if the person in the images is an adult. Whipping out your junk in public to someone nonconsenting is a crime. The line between what is allowed and disallowed in sex is drawn at consent.
Some guys like anonymous sex and will meet up from a dick pic - no face needed. Send one via Grindr and you may get blocked. Unsolicited XXX pics are the subject of endless debate.
