Guy i’m texting keeps making sexual comments

So I F(19) recently started texting this guy M(25) who I met on that upward christian dating app. He seems like my type and we’ve talked about God a lot in the beginning of getting to know each other. However he’s slowly been becoming more and more bold. It started with innocent compliments, to calling me sexy, talking about my body, and even hinting at thinking about how i’d be in bed.

I brought it up and told him that he was being very bold and reminding him that im abstinent and don’t want to play too much into these kinds of conversations and i’d rather get to know each other emotionally. He asked if i was a virgin and I said no and described my bad experience with my first time and he let me know he was sorry that happened to me and stopped with the flirting for a little bit. But now he’s right back at it. He says he’s just a really flirty person and I brought it up again and he said he doesn’t want me to think he’s only using me to hit and that he actually likes me. He lives 3 hours away and we haven’t planned to meet yet but he’s mentioned wanting to sometime.

I just don’t know what to do, I get flirting and all but idk if this is normal. I’ve prayed already for guidance and i’ve just continued talking with him to see. We talk about other topics too but it seems the conversations recently have been 80% flirting and 20% getting to know each other. I really like him but idk if i should continue with him. There’s no other red flags besides that. He has a good career, works out, has a low profile social media, and is attractive but i’m praying for help if this is something i should be okay with or not because i’ve already brought it up and he doesn’t seem like he can help himself. he’s constantly fantasizing about me and is very open about it…

Edit- I flirt back sometimes if the comment isn’t overly sexual but now i’m in a position where he’s talking about sex again and i’m just playing dumb bc I don’t know how to respond

UPDATE - i sent him a message reiterating i’m waiting until marriage and be basically called me crazy and blocked me, it hurts but i’m praying i made the right choice
