I share your desire not to get attached to a serious relationship. Pay attention to social networks and parties of interest - there you can often meet people who are looking for the same
I always use only one dating platform, with the coolest features and security system. I also advise you to create your profile on tendermeets.com . It is easy to find girls here who are not looking for a serious relationship but want to have fun. The site has a good search system: you can set up filters, for example, by interests or location, and immediately find people who share your views. This is a cool opportunity to make more acquaintances.
