If you are an investor you look elsewhere for a date.
If you actually need to worry about something being considered sexually harrassing, you definitely need to reconsider how you approach women. It's really not that hard, I've dated numerous co-workers over the years and never had any fears over that or issues when we broke up. Be polite, not over bearing and be respectful. The time will either present itself to ask or it won't. If it goes your way, great. If it doesn't move on.
