How much do girls like making out?

im 18 and my girlfriend is 17 and we've been together for 3 months. Anyways, we would always kiss a ton for long periods of times but rarely any toungue action. But today things got intense so i slowly put my tounge in her mouth and they brushed back and forth and i think she enjoyed it. But i still feel like maybe i scared her off or something. She didn't stop me or stop kissing or anything until she told me we should check the time because i had to go. Do you think she enjoyed this? I really did. we were dry humping at the time as well.
