Knowing someone for 10 years then deciding to see where things go. Is it a good idea?

So Iv known this guy for 10 years. We get on really well have a tiny bit of a flirt but we’ve always been very professional as we work together sometimes. We recently spent a week together on holiday with some friends and since we’ve come back things have really changed we are constantly text flirting, cute stuff and some sexual stuff. He said he would love to see where things go and thinks his mum would love me if I ever meet her one day stuff like that. We’re planning on meeting up soon just the two of us and then after that we’re going out with a group of friends.
Would it be wrong of me to sleep with him? I have said I’m nervous about things now changing between us as I wouldn’t want anything to affect our friendship and he said it won’t if we don’t let it.
