Gang gang

So ....This guy I just started seeing expressed to me that he's intrested in participating in a gang bang with me. At 1st I was really taken back but the more he described it the more logical I felt about it: He says he wants it to be like we're all going out on a date or they all pick out something cute for me to wear lingerie cute dress to go out to eat have drinks go back relax a little they massage me and then they all start taking turns having sex with me. He says mainly will supervise and that he will always be within line of sight and will occasionally step in to check on me and kiss me on the forehead to let me know he's got my back. He also said he wants me to enjoy it and he encourages them to go down on me as much as I need to continue (its four guys, his close friends). and then at the end he says that he and I can leave and go sleep by ourselves to do aftercare & cuddle.

Am I crazy for thinking that's a "cute" way to go about it? Should I be asking more questions? Should I be offended? Idk how to feel but id really like advice since its so taboo and my family/friends would definitely judge
