Would guys be ok with being stuck in the "Friendszone" if they were getting cooch?

sorry for bad english

Basically....i hear guys complain all the time about being in the "friend zone". From what I've learned being in the friendzome means one wants to be more than friends (romantic partners) but the other one wants to stay friends.

But do guys really want to be romantic partners and be in love or do they just want to get laid. Would you be okay if your female friend would sleep with you but would introduce you to everyone as your friend?

Do guys who wang out of the friendzone mean they actually want something serious or just vagina?

Hope this doesn't sound offensive. Thanks for answering
