My gf says she got wet just by making out with me.. was she lying?.. Is it even possible?

Ok. I mean I am her first bf and It was our first time making out.. we made out for about one hour.. stopping only to take a breath.. and all of a sudden, she says STOP and then goes to bathroom, comes back and has lost all her interest in making out.. she leaves and then next day, we go on another date and everything's normal.. and that next day she tells me that the other day she just got wet for the first time and wasnt sure what to do.. so girls or experienced guys: what do you think?.. I mean we were very pionate when making out and all.. I was even and her *** while making out.. and just before she went to bathroom, she seemed like she was about to have .. but i just dont know.. i mean if she cant handle some cuddling.. how is she gonna last during ?.. any input is appreciated.. thanks
