Yeah, I think it would be more like just lying about one's past for sex. Perhaps a little skeevy, but not rape. A new love interest would probably be the best choice for that reason, and additionally it would make story sense, as Otto probably has no inclination to continue living Peter's life, he'll want to go out an make his own way.
I think Felicia could definitely work as a love interest as you outlined, but it'd still take Ock pulling off some pretty mind blowing acts of heroism beforehand for her first instinct to be hearing him out rather than running to the Avengers or something. After all Ock has been a terrible personal historically, so she'd be crazy to trust him right away.
I'm still pretty uncomfortable with the idea of Ock doing all this in Peter's body though, I'd kind of prefer it if he was just more or less asexual, as unlikely as that is.
