NEED ADVICE

So I’m talking to this guy and he’s super cute and so nice. I’ve never met him in person though, we matched on Bumble. The only thing that bugs me is that he low key wants to have sex. He’s super interested in me but I have never expressed that I want to do it with him because I am not really interested in having sex. I am a virgin and I don’t want to lose my virginity until I get married. I have nothing against people who do have sex before marriage... I just want to keep part of myself innocent. I don’t know how to tell him my intentions without the possibility of him losing interest. If any of you have any advice that would be greatly appreciated. My my worry is that we will meet and he will expect to have sex and I will have to tell him and I won’t know what to expect from him in person. Gah. Send help.
