THB, I'd start to scratch my head about anyone who get into the double digits for partners. To me, it says the person is either a hedonist or lacks the ability to discern what a good partner looks like. The former is fine, but not what I'd be looking for in a partner. The latter says they don't know what they want, which suggests they need to sort out some things about themselves before being ready for a stable relationship.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
