Little Surprised!

Breanna • Hello! 🌸💕
I'm a little surprised!
I'm deeply in love with my boyfriend,  and we have been together for about 10 months.
I always asked him about his sex life, but he didn't want to tell me because he saw no need - he was also afraid of what I'd think since I was a virgin and quite reserved, and he was not. It doesn't matter to me though.
He finally told me something, he told me he used to talk to girls online and he would say anything to bed them, and then he would act like a complete jerk after. He also told me he was part of a 4-some, and has had close to a dozen partners.
Now, I don't have bad feelings. I just feel surprised!! He never seemed like the type at all, and he was always so gentle with me. 
To be perfectly honest, I find it a bit attractive, knowing he has experience and I don't... 😅
Anyone else have a similar situation?
