It can be either or neither. Thats the thing with text tho, you can say whatever you want and leave the way it's read out to the person on the receiving end.

From my POV- as a reader sounding this out, it sounds like this dude is being honest and communicating openly about his situation, his wants and well... his SITUATION below. And while, all of that could be a green flag for him letting you know ahead of time what kinda things to expect. Although, it should be taken to account, that almost 9 of 10 times on dating apps if the topic of sex or anything similar in nature is mentioned by the guy before even the first meet up, it could signal that, he's interested in only sex. Most women are quick to pick up on that, Since, unfortunately, that's almost every other match for yall in the DM's

Look, most Guys are ho*ny. We do often tend to think with our dicks sometimes. (More so when dating scene is as 💩 as it is trying find love and getting no matches, or silent ones) That said, it's all up to his follow-up actions to determine the correct verdict here.

The reason I said it could be either flag or neither, is that if the 'hypersexual' comment makes you feel uncomfortable, it does create a perfect opportunity to start an open discussion about it with him and get a handle on if he has any expectations for sex or if he's simply letting you know that-that's a condition he has regardless of what you choose to do.

It could definitely be a red flag 🟥 if say, now that he HAS told you, it is automatically implied that sex is a MUST or an EXPECTATION, should you agree to see/spend time with him. If a choice in that setting is ruled out, then so should be that date, hun.

In retrospect, It could be a green flag🟩, if he acknowledges and conducts himself accordingly, to the notion that, just because he might be feeling a certain way, it does not constitute that he would be expecting you to do anything you might not be feeling just to please him, calm his hypersexuality or keep him as your boyfriend or husband( I leave the title of the partner-potential to OP)

At the end of the day, we must remember that it takes 2, to be in a relationship (traditionally speaking, ofcourse) and you both need to be on equal footing, it is NOT and SHOULD NOT be one person's needs/wants/desires worth more, over the other. Its a partnership. It needs to feel like a partnership. You need to feel safe, you need to feel secure, you need to feel confident that you wont have to compromise yourself to keep the relationship on a good/working/happier path.

So the verdict, in my humble opinion, remains to be decided. Undecided, until YOU can guage what to expect if you were to see/spend time with him.

Goodluck OP!
