I've read the autopsy report and dont' recall the part about the bit about ejaculation but I may not have read the same thing everyone else did.
The photos do look strange and have always bothered me. I think she took her own pictures - but I don't think the bed scene is totally staged. His fingers up in the air seemed like he was speaking and using his hands - not making a gesture JMO
As I looked through the crime scene photos last night, something struck me. The closets are open and I really think she hid in the closet - hopped out and surprised him. Granted all the photos line up with the sequence of "psycho" (I'm not joking - it's 100% lined up) but the closets are open yet all the stuff on the counters, his robe etc are put away.
I'm starting to think someone else knows what happened that day - someone she's got something over them. It's like we are missing 1 piece of the puzzle, but being the way she is - I don't know that we'll ever hear it. Granted it's none of our business either.
JA's purpose was a smear campaign against TA and it's all based around jealousy. For those that don't see him having sex with her, I hate to say it but ... that's exactly how an unhealthy relationship stays above water - sex. Someone (forgive me, I dont' recall who) put it perfectly: They were in a toxic relationship, people told him to leave her, JA promises to change and to stop it - she realizes her wrongs - TA sneaks around (due to humiliation) to see her. They continue to have sex.
I've often wondered if she stopped over to give him a car payment (that being the excuse) and that was her "in". Anyway - I'm SHOCKED at how long this trial has been ongoing. Geez!
