How do I ask to define the relationship (31F with 31M/32M)

TL;Dr: how do I ask my 'talking stages' what we are?

Yes this is embarrassing at my big age. I know. Now that we're passed that, I'm a 31F. It's not that I was big into purity culture, just that I didn't date before. I can't explain it, I just didn't want to and really focused on my career. Anyway, in the last year I really started dating and I've been enjoying it. In July I met C (32M) and two weeks later I met B(31M).

Because of a series of unfortunate events, I haven't seen either of them as much as I wanted to (6 dates with B, 2 proper dates with C), but we talk all the time. Anyway, C has been really clear from the start about wanting me, and recently he's been indicating he'd like to see us take our relationship sexual. I'm ok with that. It would be my first time, but it's fine. I really like him. B is equally as wonderful, and we've been talking along the same lines. Apparently I'm in the talking stage with both of them - I don't get it either.

Why am I seeing both of them? Because neither of them have given me an indication about whether we're anything serious... (And honestly, I probably don't give an indication either because I don't have experience) and I do like both of them...

Anyway, I think it's time to ask, right? Or is it too soon? I am not into something short term and especially sexually, I just don't feel comfortable without some sense of direction...

So my question is how do I do it? I asked chat gpt because it's so embarrassing to not know how to do this, and honestly I got something so lame.

Relationship gurus, please tell me how to do this. C is out of the country, B is leaving soon, I know I need to. Do I do it in person? Over the phone? Text? I know this is the internet but please be kind about my inexperienced, I'm already stressed enough and trying my best to not lead either of them on, and still figure this out.
