I want to give you some support here.
It’s perfectly reasonable of you to want friendship and not want to have sex with every guy you are nice to.
Unfortunately, many, if not most, guys will think that you are hitting on them if you are remotely pleasant.
I suggest that you wear an engagement ring, unless you are looking to date.
Also hang out with gay men.
Women are more complicated and this can make relationships with them harder, but if you can find a female friend, those friendships can be very rewarding.
