It's probably cuz you don't take risk at all, I don't even understand why they want you to be so conservative in their liberal relationship with him...That's probably why she's gambling with sex dice at your family members house while there gone because he wanna clams someone about you like he feel the same. damn I bet you they got a fridge full of asparagus because it only tastes good when it's cooked on a skillet, having a sexy ass date because you want to be poking her so much with your dick and the reason why he like that guy better is because he cums in her the first time. Just eating all the goofy insides feeling her deep because he wanna be injecting his dick with hydroloric acid because how it makes his dick soft.

It's also a reason for female to not get mad if a guy do it cuz if she do... She's probably cheating or needs a dilldo or something. Because some dude complain about condoms like it's the most painful thing so be aware and if your not she must be very superstitious for allowing you to do that so she could argue it.
