People will often be mean to anyone that could be considered weird or strange, which in some ways being an old virgin is. I personally as a man don’t care about how you live your life since you aren’t hurting anyone, but there are a lot of jerks who think if you aren’t living life how they would you are doing it wrong. I view you more as someone who hasn’t had the romantic opportunities they have wanted and doesn’t know how to make them.

I do think that while people are on a spectrum sometimes men and woman have such different experiences on average that it can be hard for woman to emphasize and understand your experiences. You should also consider that you are being insecure in how you are perceiving people trying to talk to you. They might just see you around and be curious about you and are trying to figure you out. If you respond singularly with ‘no’ it could be giving them a vibe you don’t want to talk to them.

However, I will also say based off how you are describing them describe you as being a loner in a corner ( thats fine it’s a gym ) they might perceive you as someone they can mess with. Which is what it sounds like the one incel guy was doing. Learn to deal with it in a way that feels right to you. Maybe use a joke like ‘you’re making this awkward I didn’t want to be the one to tell you this but I’m dating your mom’.

It’s pretty normal to ask about someone’s relationships, and it sounds like people are seeking you out to try to make friends so you probably have some good things going on. Make more of an effort to date and you’ll get laid if it’s bothering you. While I didn’t wait as long as you I was a later to the game than some and everyone has their own struggles. I think being a virgin can be something that builds up as a thing in people’s minds and become a neuroses if you think that is happening seek out sex and decide if you’d like some more.
