I dreamt last night that I had sex with one of my closest friend's ex girlfriend. They've been broken up nearly a year now and we've kept in touch because we became quite good friends ourselves throughout the year they spent together. She's a naturally quite flirty girl and she is very pretty, but being my friends ex I wouldn't dare to go there. I've always been afraid to think about her in a sexual way but in the back of my head I've always been curious and thought what if? I'm only 18 so I'm quite confused and don't really know whether I'm coming or going with the whole situation. In the dream we were alone in her room and she was flirting with me and trying to seduce me. I asked her what my friend would think and she said to not think about that its not that bad so I forgot about him. We did it and it was great, it was such a good dream and it was all I've thought about today. I'd nearly love to have a similar one again! But at the same time I've been feeling guilty and don't know what to do or think about it. Any help or suggestions would be greatly appreciated because its been so annoying with all these feelings going back and forth, thank you!
