Then I never want to be in a relationship (well I'm AroAce anyway but). I have friends, guys friends that are always here for me and I'll be there for them. We play games, hangs out to play ygo or buy cards or watch movies yet they never saw me as a potential love interest and I won't see them that way either we are just friends. Gender doesn't matter, what matters is that people know and apply the difference between romantic and platonic love& relationship.
Your mindset is way too restricted. Not everything revolve about being in love or wanting to sleep with someone.
Dunno about your friend group, but there are there only guys? If so you will probably see few things:
1) You will maybe eventually learn that some or one of the guys liked you.
2) They will eventually drift away from you
Despite "new liberal wave", when we get in our 30's we seek more or less stable and secure relationship.
I for example was hanging out with a mixed group, eventually this group became exclusively male. Why? Well it was out of respect to our partners and natural alienation. I cannot confide or joke around many things with women, physical differences and how you or the world perceives you makes you incompatible in some ways. With our respective partners we are willing to close our eyes to those differences and try to understand them with friends? It's a matter of convenience why should i stress with friends?
Also before you say this statement I wish to tell you and ask you to do 1 thing.
1st I wish to tell you if you are in school or aged under 17-18, your experience is invalid due to the reason that people under that age still are figuring stuff out. I had sexual experience and was exposed to adult content at a very young age but as for romantic feelings? Maybe my first time was around 21-22. We also had some girls in our group, but eventually we split apart.
I for example would not ever visit or invite a woman out or in if she has a partner (excluding when her partner is present). It's a matter of principle and respect. With many of the girls in our group i had friendly relationship we partied, drank, drove somewhere and etc. but never truly one on one and when we had one on one it became apparent that one of had feelings for the other.
Happened to me, to a lot of my friends and etc. When the cat was out of the bag, people who were rejected eventually drifted away. They stayed in the group for a long time simply because they developed a "crush" they were not so much interested in the group as they were interested in other person and when faced with rejection it was easier for them the whole group altogether rather than stay in a group with a person who would cause the constant heart ache and reminder.
As for what i wanted to ask you to do. Please do a social observation, who laughs at your jokes more, who invites you more, who tries to talk to you more and who while laughing looks at you. This person might be the one who developed his feelings for you. Since you AroAce or in common terms asexual you probably told your friend group, thus the guy who developed crush on you was rejected by default by your statement and looking by the hobbies' you have(as a group), i doubt that people in your friend group are assholes or courageous enough to trample your identity (try to pursue you despite your stance on romance or sex).
Friendship between sexes is possible but in a vast majority of cases one is "friends" while other has feelings and is either waiting or tries to outlive feelings of love(while doing so experiencing pleasure by being near that person). It's like being stranded on an island with the other person, eventually you develop something, sadly we humans are built like that. A lot of cheating simply happens because for example you work 8-10 hours with the same person whilst you only have 1-2 hours of your time with your partner and due to weakness of your mind you cross the boundary of cheating.
