Is there any way to know for sure that a girl is ready to be kissed for the first time? Any way to be 99.99% sure, little to no chance of rejection?
When should a guy feel comfortable just going for it?

Too make sure you don't get rejected when you try to kiss a girl you should try to read her body language first and you should have built some kind of comfort level with that girl before you go for the kiss.
For instance. If you haven't even touched the girl in any way it's more likely that you will get rejected. I don't mean touch as in groping her or anything sexual at all. I mean casual things like touching her arm, shoulder, knee etc. Girls do this all the time when they try to signal interest.
A classic example of a girl interested is then she laughs at a joke you make and at the same time she touches your arm, shoulder or similar. This is her showing that she is comfortable around you. A girl that has touched you like this and not have been creeped out with you touching her the same way will most likely not reject when you kiss her.
Take small steps to build comfort and try not to jump the gun.
Build comfort by escalating touching (nothing sexual in this stage). Notice how she responds when you touch her. Make longer eye contact. Notice how she looks at you. How she positions her body and head in relation to you. All this builds up to a kiss and if you take notice and follow all the steps you don't have to worry that she will reject you because her body language and behaviour have already said yes.
Good luck making out :)0
