Is it normal to only have sex if she allows you to cum inside her?

I get off by getting off inside a woman. If I have to use a condom or pull out, I continually lose my erections and can not perform. That being the case, I have not had many partners. The only time I will have sex is if it is a committed relationship. I pass up casual flings and one night stands because in my opinion, they are not worth it. I have to pump it in my partner as hard and deep as I can. Even when masturbating, I have to watch creampie porn, and I can not climax until I can see the penis pumping when the guy cums. I can't stand the creampie porn where the guy pulls out until it's just the head of the penis inside when he cums. The only way is to push it in as deep and hard as you can. Is that normal?
