Threesome as a virgin F

[newtoallthis]

Hi,
I've dated guys before and I've tried to have penetrative sex with one of them before, but due to some unfortunate circumstances, it didn't happen. So, although I'm not entirely inexperienced, I'm a virgin in the traditional sense of the word.
I have issues with body shaming and I have a hard time imagining that the guys I'm interested in, could be physically attracted to me. In any case, right now, I'm not emotionally there yet for a long-term relationship.
So I was looking around on Tinder and found a couple who's looking for a woman to have a threesome. And I'm totally interested. I've been wanting to try sex with a woman also for a bit now, and with no scope of emotional entanglements, this seems like a perfect opportunity to get laid with both a man and a woman.
Since these people are strangers, however, what do I need to keep in mind to be safe (sexually, physically)?
(This couple has been in a foursome before, they've told me.)

Hi newtoallthis,

So, while it sounds like there are elements of this situation that excite you, there are a few things about it that give me pause. For starters, it sounds like your personal sexual experience is limited. There's nothing wrong with that, but it does mean that you've had relatively little practice communicating (or experimenting with) things like your desires and boundaries. Being comfortable with that kind of communication is important in any sexual encounter, but especially in one as potentially complex as a threesome. Too, if you know you've had issues with body shame in the past, it would be sound to consider how comfortable you'll be with being vulnerable around two people who you don't know that well. It's not that having negative feelings about your body means you can never engage in casual sex or sex with multiple partners, but situations like those can potentially cause a flare-up for your body issues. Do you get what I'm saying?

If you were to decide to go through with this, you'd want to meet the couple somewhere public before anything sexual happens to get a feel for them and the dynamic between them. You'd also want to discuss limits and boundaries ahead of time. As for safer sex practices, you'd want to make sure that all partners agreed to use barriers (like condoms) for all activities in order to be as safe as possible.
