I have slept with a number of men (between 10 and 20) and only one has ever tried to pin me down and he stopped as soon as I said no - I'm claustrophobic so I wouldn't tolerate this.
I have had a couple try to initiate anal sex without having checked first, but again they have stopped as soon as I said no.
I have had them ask for things I am not interested in, but whilst they may have pushed a little verbally, they never forced me to, or physically tried to make me.
I have however also been raped by one man. He did force me and didn't stop when I said no and when I was clearly distressed.
I understand why you want to think that this kind of behaviour is normal. And I'm not saying it isn't widespread, you only need to see the volumes of people being raped and sexually assaulted to know there are plenty of people out there who will try this.
But in a healthy, consensual non abusive relationship these things are not a normal party of an everyday sex life.
My partner has currently lost his sex drive and to be quite honest its frustrating (although I would never tell him that). What I am managing to do though is be a decent person and not tear his clothes off, pin him to the bed and force him to have sex with me. Because I love and respect him. And because I am only interested in consensual sex.
You sound like a very vulnerable person who needs help to get out of this relationship and to not fall prey to this kind of man again
