Not sure what happened
Background on us: we've been together for 3.5 years and have GREAT sex. We go for hours at a time and both orgasm numerous times.
We recently had our 4th mfm encounter. The first three were "meh" as the guys were just not a good match for us in the personality department. This all started because she wanted mff but it's basically impossible to find, so we tried mmf instead. During our most recent encounter things were different for her. We had a pretty big argument right before hand at which time I called it off. She insisted that since the guy traveled a long distance, we needed to continue. After he arrived, she began sucking his cock and was amazed by the size. I wasn't feeling the situation, so i went upstairs. She came upstairs after a short time and told me we needed to continue. I again said i wasn't into it at all, but she persisted and i gave in. The guy was not super attractive and was definitely not her type physically, but had an enormous dick. I'm above average, but he was huge, probably 9 inches. Anyway, she wasn't able to cum from sex with me at all but had no issues with him. There were numerous times he was in her for less than 10 seconds and she was cumming already. We talked about it after and she said it wasn't from his size, but just because the encounter was "hot". This doesn't make sense to me, because if it was just the encounter then I think she would have been cumming regardless of who was in her. She also did things that weren't necessarily off limits but that she had said prior that she wasn't going to do(kissing, eating ass, anal). I also got the feeling during the encounter that my presence wasn't important. She definitely focused on him the entire time. Having some trust and inadequacy issues now. Can anybody chime in on this?
