How to talk to boys!!

I am 18F, never had any conversation with the male species apart from my family members.

In my defence I have studied in an all girls school and I still do.

Up until 7th standard I didn't knew about relationships and all but then few of my classmates had boyfriends was happy for them but I didn't have fomo or something so I was content with my life and then heard about few breakups some of the breakups being very public, after which I had lost whatever intrest I had in relationship.

Then, I realised I don't know how to act normally around boys like I sometimes act as if these boys are from another planet like I am very aggressive and all in my behaviour though I talk sweetly to girls so I am not rude by nature😭.

I thought I can atleast talk to boys virtually but how to do that
