SF normalized being 30+, successful, but still living with roommates. As long as you have an adult relationship with your parents (aka they're okay with you having sex, and you're okay with your parents having sex - which they most likely did in order to have you) while all living under the same roof, then it's fine (assuming all parties involved can get over it).

The problem with dating while living out in the 'burbs is that the population density just isn't the same, even if you don't mind driving. Apps help in this regard. There's also the practical matter of alcohol. Taxis (inc Uber/Lyft) just aren't as convenient outside of the city. There are more parks to meet at though!
