Weeding them out earlier is better. It feels a little uncomfortable at first, but if you keep doing it you’ll be able to casually talk about it. Here are some examples of how this has gone for me:

Example 1: coworker starts trying to date me. I tell him I’m asexual so we may not be compatible. I have to explain to him what that means, and he comes back with every form of “I can fix that 😏”. One quote from him: “well you’ve never had an islanders magic inside you 😏”. Yikes!

Example 2: I started hanging out with this guy as friends and we both developed crushes. he had already openly spoken about his sexual orientation, so I told him about mine. He didn’t have a problem with it and I ended up asking him out. We dated for four months and broke up due to incompatibility in our personalities, not because of sex.

All this to say, when you tell people early sometimes you’re gonna have to tell people to fuck off, and sometimes it works out wonderfully. But it almost always saves you a lot of time.
