I'm single. I've never dated. If my first dating fails I might date again but again it will be sexless dating. (My type of sexless dating is dating without having any physical contact to the private parts). As a virgin I might have more than 1 romantic partners at a time but once I get married I won't ever have a 2nd sexual partner not even if my husband dies.
So the advice of test driving in my case is meaningless.
