Well, my husband is about 5'11 and about 180 pounds very well toned and lifts some weights at the gym. I'm 5'4" and about 117 pounds well toned, I swim, ride bikes and play tennis but not super muscular. I think it would be a stretch for me to throw him down and make him fuck me, let alone be able to inject his penis with a caverject while holding him. If we were more equal in size, I would consider it if I needed my daily screw.
Sex is a marital obligation. It's nice when the feeling is mutual but it doesn't have to be,
Although I will say plenty of smaller women have killed their partners with a handily placed knife, scissor or other sharp instrument while having sex, so I guess it would be plausible for me to inject him if I had to! Of course, he would probably have to be tied down first, but the likelihood of that happening if sex was not on the table is also pretty remote.
Luckily, all I need to do is to extend my arms holding my wrists together and one of us is going to get tied up.
@SwitchableSusie :
A Jewish friend of mine told me there's a Jewish law which states that if someone violates the Sabbath, they shall be put to death. In fact, no one has ever been put to death for violating the Sabbath.
I'm sure in the old days, plenty of people were put to death for not observing the sabbath and for much lesser "crimes."
I am also told that in the Old Testament the husband is required to "service" his wife. In fact "service" is also the legal term people use when one person is injured and they want to sue someone because the wife is unable to have sex ("service" 😉 her husband.
