I am very confused about a recent event, and am wondering if I'm a cuckold or I just like having intense sex with my GF. We recently had a threesome with which involved her EX. She took his cock in her pussy while sucking me off and kissing me...

I got pretty hard. looking at her body getting pounded while she had my dick in her throat..

Later, after he came in her, she asked me to fuck her pussy with all his semen still in there... This was something I was hesitant with initially, but I went ahead with it because I was pretty horny and she was really keen about trying that out.

I went ahead and fucked her semen-filled pussy, and she felt so warm and wet, and the thought of other guy having cum in her, made me more horny and I became rock-hard. I came a lot more than I usually do, and the intensity was also way higher.

She loved it a lot and was moaning louder than she usually does and eventually came on my dick, while it was in her pussy, covered with her ex's semen. She want's to do it again. I loved the experience too and want it again. Though I was bigger than him and there was no power dynamics play I enjoyed it...

Am I a cuck or am I just freaky?
