Hi, I'm not an expert, but that's my contribution.
I would say the guy is a maniac. A sexual maniac, because Venus (him) is in his 9th house, which represents his mind, way of thingkin, making an opposition to the moon (lunatic, problems in his mind) which is in Leo, enhancing sexual rapport.
I would say a man trying to rape you. Be careful, because he can come back again, if he hasn't forgotten you. And you know, obssession is dangerious.
