Are you kidding me? If this is worth a thought in your head, then you need to re-evaluate your life.
In regards to my own personal experience, I believe sex before training isn't beneficial to my training due to the relaxed state it puts me in. However, it does provide a good warmup, but I like to think of my training as a warmup for bed!
