I agree that friendships with women can be really fulfilling, but I've never had it work long-term without lines getting blurred and usually instigated by the woman. Friendships with men are reliably less complicated.
Of course I mean just true friendships, not some hunting for next partner in disguise (or something I saw quite often - keeping group of 'friends' around for next loneliness period to choose next partner from - both men and women are equally guilty here, there was always some weird little dynamics happening under the bonnet).
Guy-guy relationship at the end can easily be 100% honest and true friendship which is what men are normally looking for, guy-woman rarely so, even if they keep acting and telling themselves its just that. Biology is not something you can keep denying for long under various circumstances.
As for the main topic generally, I'd suggest either joining some group of people practicing sport one likes, or even better organize something for others. If you want dating, women will notice, they always like seeing competence and self-sufficiency.
Women - if you have good close straight male friends, and you are at least a bit attractive - don't think for a second they didn't at least once have a fantasy of having sex/dating you, most probably more than once. Maybe not 100% of men, but 98-99% for sure, we are not that complicated.
I'm guessing/hoping you are fairly young because though I can see how these perspectives make a lot of sense in the early part of life, by the time we are adults we should view these ides as simplistic and silly.
