Friends with Electronic Benefits?

Okay ladies. So I’m 18, and I have a guy friend I’ve known for a long time. We live a bit far from each other so we see each other about monthly. Last time we saw each other, things got a little hot and heavy. To make a long story short, a passionate make out session was had. However we don’t have feelings for each other. Now we text and Snapchat, and it leads to sexting. He used the term “Friends with Benefits” which was very interesting to me, because I’m not a person who sleeps around a lot...

Should I end this situation to save our friendship? Am I being slutty? Advice?
