I could be wrong but I feel like false rape accusations are more likely to happen when you have a lot of mutual friends/you spend a lot of time with her so she's more familiar with you. If you're strictly reaching out to women cold contact be that on dating apps or approaching in public, charming them enough then moving on, then your risk is greatly reduced. Obvs most girls would never do falsely accuse. But it is risk in general to if you want sex. And for goodness sake yes please wear a condom!
