For sure.
There are also whole sub-cultures where that's pretty much the norm. No fear of intimacy, no trust issues, just culturally normal for a lot of different reasons.
f*ckbuddies are part of a military sub-culture, for example. Free & readily available healthcare, short stays anywhere (from as little as a few days to a few weeks, relationships are rare unless you're somewhere a few months for them to last), stress relief, & the whole might be dead tomorrow thing... All very much support an open sexual culture. People are still decent, there are rules involved, they're just very different rules than you find in other populations. Including other sexually open sub-cultures.
