My first sex at my early 20s, just few years ago with a dominant/top guy, was scared and bit rushed. We got naked and I deep throated his 7 or 8 inch cock, without condom. I was new to this so I thought the taste of his cock wasn't really as I would've expected then.
Later I got fucked in the ass bareback in all four position, for the first time I suddenly realized how painful that was! He did asked me if I want to get cummed in the ass, I was again scared so I said probably not, so he shoot on my chest and parts of my face.
I knew it was an unsafe sex, I guess I was too horny to think about anything at the time, I was just wanting to get screwed by a man's cock that's all I thought. Foolish, sure, so later I went for blood test and a second time of HIV test three months later, all went ok so I was relieved. So from then on, I decided no more unsafe sex anymore for me.. and would also strongly recommend everyone not to.
