I'm not sure what advice I can give, play the way you want, I always go the corruption route because I like taking a dominant position (DON'T be submissive to Vanessa though without saving first (you WILL need to reload that save after watching that scene), it will cause later content with her to glitch... you'll have to wait for her to invite to a second date, which will never happen in the current version).
Be careful if you decide to cheat corruption/love values, making them too high too soon can cause some scenes to be skipped because certain girls will only spawn in certain locations if their Love/Corruption are within certain ranges. (I do tend to cheat those values though so take that for what it's worth)
