Where can you have sex, if you still live with your parents?

My bf and I have been together for some time now. We both still live with our parents (we live in NYC &rent is not cheap!) and don’t want to be disrespectful when it comes to having sex. My dilemma is that idk where else we can go. My bf had to get rid of his car because it had a lot of issues due to an accident. I also don’t have a car at the moment. Any ideas on where we can go to be intimate? My bf & I are in a really great place in our relationship, and I don’t want any issues to arise due to our lack of intimacy. Any advise would be great!
