Would a guy you're dating get scared if you tell him that u want to be exclusive?

The last guy I asked actually ran away. That

Only shows the level of immaturity at its finest. If you're ready for an exclusive and he's not let him go and move on ...there are so many other guys out there ...don't waste your time on one person whose not looking for exclusivity ...it's up to you if you're comfortable with knowing he's talking to other girls. So Kay out the cards on the table and take whatever action is needed.

if he is genuine you NEVER need to ask that he is "exclusive" from the first time you go out ---- to me its an insult it says i have no integrity and that i have not been honest with you ---- men are not skittish --- boys maybe

It's very likely. Males are skittish creatures.

Depends on how old are you two...
