Flirting or sexually flirting

Hey ladies so I don’t understand what’s going on w this boy I used to work w. He’s really sweet but he flirts w me sexually On some occasions he just acts weird. Apparently when we worked together he said to a coworker I was cute but he didn’t find me attractive that way and that he would never date a coworker. After my coworker asked him a question about about me and he gave that response he didn’t really text me much after. But now that it’s not really awkward because it’s been 2 months ago that it happened he’s all chatty again. He even says sexual stuff to me which turns me on and I flirt back but I don’t really think he likes me that way. He always claims he’s so busy to be in a relationship. But my friends think he doesn’t ask me out or anything because I’m (17) a minor and he’s 19. They think he just wants to have sex when I’m 18 but I honestly don’t understand what he is doing. Sometimes we will talk and I let him initiate most conversations and sometimes when it dies I’m not the type of person to continue after an lol message but when I leave him on read after a message like that he will still continue it. He doesn’t say sexual things all the time. But whenever he is in college I don’t message him I let him reach out to me when he’s done w his stuff. Point is I don’t cling on to him or do anything for him to talk to me or flirt w me. So my question is, could he possible like me and it’s just not the right time or does he just flirt cause he’s bored or just wants sex?

Here’s something’s he has said to me that sounds like sexual flirting

Me: it’s 12 am why am I awake my body woke me up or something

Him: because your body knows me

2nd time

I send him a picture along w other streaks on Snapchat in child pose stretching for a dance show that night

He responds w “hot” (keep in mind

Idk if he was joking or serious)

That same night he said... don’t break a leg when performing I told him I hope I don’t break my hips because I have to do a split in the dance and he said: oh ya don’t break those, hips are important

And I replied: very very important

He replied: very very very very important

This is not sexual but makes me question whether he likes me... he was asking to see my prom dress like 3 times and I wouldn’t show him and he was like c’mon plz at least send me the link to the dress online. I didn’t show him til prom day when I sent him a picture of my look and he said: ooo I see you, popping off. Beautiful.

That’s when I was thinking to myself awe he’s sweet

Another time that did seem sexual was a couple of nights ago he sent me a game on snap to play at like 8pm never played the game.. left him on read actually. It was 10:30 at night when he texted on snap: play with me

And I said: play with yourself and he said awww :(

So like I don’t understand. He says he’s too busy. He hints that he wants to date someone who’s bilingual and Mexican and I’m both yet I don’t understand why he’s not asking me out if he does like me I just don’t get it
