I really don't know what do people talk about and what should I talk about if I want to date someone

Background

21M I have been single for my entire life and really never had friends around my age group always had people elder then me around 5-15 year elder because they understand me and only used to talk all about technology.

Recently talked to my therapist and she told me to make some friends so I tried and made 2 friends and I am roommate with one of them and he is fun person for others but his I get more depressed about how he talks and topics he talks about and just watches serials on other hand I watch educational content on buisness, mindset, technology, physiology and more.

**I am really a shy introverted person unless you talk about technology and engineering where my other classmates don't speek out I tend to be completely opposite.

Most of people around me tend to disrespect girls or label them as something on other hand I respect them and see them as a normal human being.

**What should I do while being respectful and funny for other person too.
