My wife loves big dildos since our first threesome with a bull

Hello there,
I was wondering if your wife is much more into using a dildo during sex with you since she had sex with a bull. For us, we had 5-6 dildos before our first threesome experience (with a black bull - 9 inches). Since we enjoyed this great life experience, we did a second threesome with another bull (white and only 7 I inches). He did a great job, made her climax a lot but she told me that she preferred our black friend because his cock was bigger. I ordered 2 new dildos:
- Jeff Stryker (7,5 inches useful length and 6,2 inches girth)
- John Holmes (10 inches useful length and 7,4 inches girth)
She loves them both a lot but prefer the John Holmes because it stretches her much more and she cannot take it ballsdeep.
Is it the same for your wife, did she become a size queen willing to test bigger dildos (and cocks) ?
