Honestly 99.9% of the time this will not end in a relationship. What hes saying is your good looking but not someone he would date. FWB means you use each other for sex, so when he invites you round its because hes horny and being the FWB means your willing to have sex whenever.
You can see other people as well and still sleep with them etc as your not seeing each other, be sure you want just sex and nothing else before agreeing to this otherwise more then likely your going to end up majorly disapointed.
Friends "with benefits" are no longer just friends. The line of intimacy has been crossed. And since it was his suggestion, you can be sure he has suggested this to others.
Rethink being a part of this situation as for whoever else he sleeps with ... you don't want what others could possibly have ... the risk is not worth it! Respect and protect is number one! I would pass on that offer and remain just friends ... or possibly move on!
As you said ... your experience has been "in relationships". You are telling yourself something very important ... you will never steer yourself wrong! That's called your "gut" feeling and we all have that for a very good reason!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
