So, your next steps are about your safety and health: emotional, physical, sexual.
Since we've got COVID going on, it's ideal not to be hooking up with new partners, period, but if someone is going to anyway, we've got info on safety for that here (long story short: vaccinations and conversations/agreements about limiting contact with others are obviously ideal), even before or without any kind of close physical contact:

In terms of your physical and emotional safety, conversations about consenting and agreements about that are key, and with meeting someone new, it's always advisable not to meet a first time for sex, but instead to meet a first time for a coffee or something somewhere public where you can suss them out, see how you feel about them at a meeting like that, see how they are during and after that kind of hang, and how you feel about them. You can also have a conversation at that meeting about what you need when it comes to your emotional safety. For instance, you know you have language that sets you off/turns you off and might even be PTSD triggers for you. When NOT in bed with someone is a way better time for them and you to talk about those then AFTER you have to deal with being set off in bed. You also can find out of someone does or doesn't have the maturity to be your partner in conversations like this: they can be very revealing.
If and when you choose to meet them again for sexual contact -- there's another conversation to be had there, likely, about safe places for that and such, but we're not there yet -- in terms of specific STIs, we'll be talking about making sure everyone's got current testing and is using barriers for genital contact, so this stuff here:
All the Barriers! All the Time! and
Testing, Testing...[/b].
COVID and this being all new AND this being someone you haven't met yet makes this a pretty big lift in terms of all the things to kind of think about and have to manage at once, but those are the bare basics. I know even for basics, that's still a lot, so how are you feeling about it?
