You need to be thick skinned - After divorcing in my early 20's and I was the same as you back then. When I wA married all of my friends were female.
However, this quickly changed. When I realised as a newly single woman how catty those tethered female friends became.
Of course being a single woman you naturally get approached by lots of Men . I very quickly found many of those guys made excellent friends. Of course you have filter them from the ones who are directly looking for fun or a relationship from them who are just cool to hang out with do and know .
You have to be thick skinned because some ppl are Jealous that you have male friends who you not obligated - others may refuse to believe you are not sleeping with them and may wish to take the moral high ground.
The guys themselves seem to instinctively know its just all round friendship . & value you as much as you do them.
Plus if / or when you do eventually decide that one of them is much more special than the others. You'll pair off ..and that will be that 😉
