I don't think they were having nearly the amount of sex she's led people to believe, Travis was a Mormon trying to stay true to the 'rules', he hardly ever even sexted with her, frankly I think the bathtub/braids/tootsie pop/pop rocks event was the only actual intercourse they shared, and think any other occasion was grinding or hand and mouth (possibly backside but doubtful there too), but I don't even think that was as frequent as the murderess avers.
One other thing came to mind, she was apparently loaded with condoms in the second rental (escape) vehicle so she likely preferred to use them - none were found at the crime scene, no empty packages, nothing in the waste cans, yet she wants everyone to believe they had sex twice that day?
What is even more telling, imo, is that I don't recall a single exchange or journal entry where condoms were ever mentioned. You would think that one of them would have made some reference to them... the need for them for cleanliness purposes(anal) let alone what I would think would be a definite no-no for anyone trying to live a religiously correct life, an unmarried pregnancy. Instead all we hear about is grinding(a form of masturbation) and how JA introduced TA to KY, something that may ease forms of penetration in those who are having anal sex or natural lubrication problems(not something I would think is common in two young people "hot" for each other), but is more commonly used to reduce friction burns from masturbation. Since JA had no qualms talking about using Tootsie Rolls and Pop Rocks, why no talk about what kind of condoms they preferred... Ribbed, Studded, Thin, Flavoured, Lubricated, Ticklers, etc.?
