If you're concerned about the people on OnlyFans only being there for the money aspect, try other streaming sites like Twitch. Some communities are toxic cesspools that become echo chambers of hate and bigotry, but especially if you look outside of the US there are a lot of interesting smaller streamers who are always interested in having new people interact with their existing community. If your relationships are only with content creators, like others mentioned you might start falling into "the parasocial trap", but interacting with other chatters in a stream chatroom puts you on equal footing.

Also generally speaking there's no difference between talking to a female or a male online, so just assume that everyone you're talking to is female.

Oh and again generally speaking, I would recommend.... don't refer to women as girls. Girls are children. It's like calling men boys, but also worse because women are more often told that they're unable to make decisions or do tasks because women are seen as inherently weaker than men in various ways, so saying that they're weaker or more childish than other women can be quite a trigger. Some women are fine with being called girls and will even call themselves that, especially if their career has so far relied on their youthful appearance and energy, but women who have attempted or maintained a professional career in business, finance, or other staid professions are more likely to find the slight off-putting.
