traveling hook up

STORY TIME: WARNING TMI So on an international tour through college I hooked up with one of my sorta guy friends. it was only the 2nd day and we were drinking and hanging out in a corner and he suddenly kisses me. and I broke up with my boyfriend of 1 year like 6 months ago so I'm appreciating the physical affection. it's was super HOT 😉and we sneak away behind this building and he starts fingering me and squeezing my ass. and then I'm touching him and giving him a hand job. I've never been so turned on in my life. we go at it until 2 in the morning and then the next day he acted like nothing happened, which really bugged me. a week later on the tour we're at the beach and he decides he's in the mood to hook up again and we're making out while I'm straddling him and we're both topless. another sexy night. In summary I've never hooked up with someone before and while it was fun I feel really bad about it and the next year that same "friend" only talks to me if he wants to hook up. and I hate feeling like just a booty call. but sometimes I'm so horney I want to give in. UGH any advice on how to deal? should I feel bad for what I did?
