A Question On Sex Magic Options

My partner and I have been curious about sex magic and although I have found some interesting information on the subject, I was wondering if any one could give insight into the more ritual aspects of it? and maybe a bit more on the subject itself, I'll admit to being ignorant on the magic portion of the deed. I know it can be filtered into forms of creation magic and general connectedness but I guess I still don't quite get the whole spectrum of it. If anyone can speak from experience (with more on the experience as a whole or ritual nature rather than details) it would help a lot,
Thank you =]

Thank you both for the information, I think the idea of marking eachother seems like it would work for the two of us rather well, and I think maybe going through the compass points and using a circle might put the magic more on mind then just screwing haha so I will definitely find an appropriate circle raising to get us into the right mind frame for balancing both. i hadn't thought of planetary alignments (I'll be honest aside from using the full moon every once in a while, I've never used 'em a day in my life) but candles and other more simple ritual aspects sound good. Thank you both very much for your help!
