No experience with other people so having any relationship with them is hard

People want to ideal version of friendships and relationships.

What happens though when we let someone into our lives who seems alright but then they just cause chaos?

It is a lonely existence but one is better off without. The drama and problems of friendships and relationships is not worth it.

Meh, ya get used to it. My GF and my dog are the only ones that want me around, or that I’m even comfortable being around for long periods of time 🤷‍♂

Nobody was raised in a healthy community. Do not expect the others to be capable of relationships, either. This is by design - you understand that's what it means to not be socialist.

You need to fo to a sex addiction support group and tell the ladies there about your struggles to find someone to open up to.

smile when you see men you like, chat to them, see where it goes

Don't let something you can't control (birth order) define you.

So now what have you decided?

Yeah, well so am I the middle child and I'm the same age as you are, but I've never had issues with having NO experiences with other people in my entire life.

Your problem is not about your big family, that's all about you and your conscious decision to NOT have experiences with other people along the way.

What have you been doing for the past 10 years, beside sitting around with your face planted in a cellphone screen, chatting with strangers?

If you had ditched your cellphone and cancelled all your social media accounts which caused this problem in the first place, you would have had no reason to make your post in the first place, because you would know real people today instead of a host of virtual usernames who never get together and meet up with you in your offline world.
