If he makes a move on the first date, does that mean he only wants sex?

[Luna66star]

I think it depends on how he generally treats you overall.  Is he trying to get to know you, asking questions, is he actually looking for a relationship or casual? 

He might be genuinely attracted to you and want more than sex.  On the other hand, he might just want FWB.  It's hard to know until you look at his actions.  With casual, he may not be in touch regularly, he would stick to very surface level in interactions,  not mention his family or friends and certainly not introduce you them.
