Should I be worried guy ignored last text?

Hi, so I’m 21 and been talking/seeing this 23 yr old since December 21st. Ever since then, we’ve been talking everyday. We have met three times. I am a virgin, which I told him and I also asked what he was looking for after the first week of talking (to prevent being hurt). He said that he was open, that depending on the vibe he gets from someone, he’ll go from there. I told him I was looking for good vibes and ultimately a serious relationship. Ever since then, when we met, it has been intimate (making out and third base). He’s been hinting at sex, esp through messages. I told my friends how I was thinking of losing my v-card to him, but they told me to be careful. Not sure if he really likes me or just wants me for sex. I glanced at his Twitter and he likes mostly pictures of thick women (I’m on the petite side).

Anyways, he would always say “good morning” or “good afternoon” usually I ask about his day, work, make jokes, etc. I last heard from him on Wednesday when he replied like 6 hrs and told me had a long but good day: I was like, “ooh okay. That’s good at least.” And it’s been nothing since. He’s been active on social media and is usually the first to view my stories. I’m not sure if he is losing interest because he was also talking sexual this day & I replied mostly with humor. He also mentioned how I’m shy to always say stuff. I told him he was the reason. So I don’t know what to do. Some friends have told me to not text him back and wait.
