No judgement please

So my sugar daddy wants to try us with another girl (we’ve done another guy and it was fun (he likes to watch), now I’ve thought about it before as a threesome. I do find some girls attractive but not to the point of it could be sexual but I’m not against it I’m more afraid to try it.

How can I rip the bandaid off and just do it, (not for the money but the experience) you won’t know if you like it until you try it. 🤷🏼‍♀️

Ps any pointers out there for a girl to do a threesome with another girl who has never been sexually with a girl (I’ve made out with others but not any further)
