When I was 13, me and my best friend ( a guy ) had some sexual experiences. I gave him head a few times and he reciprocated, and we also used to masturbate eachother's penises.

I am straight.

I wanted to know if other people have done this in the past.. or should I be worried about what happened?

I'm female, and I had a similar situation with a female friend when I was about 14. I'm straight too, 26 now, married and expecting a baby. Personally I don't think you need to worry. It's normal for young people to experiment this way. It might seem embarrassing to talk about it later on, but you'd be surprised at how many people have had a similar experience when they were an adolescent.

I should be all right. Any way it is the past.
