Some can. It's probably a very different experience though.

And many women can't. If it's unknown to the rapist, asserting power through a threat of forced pregnancy might still happen, but if she's like sixty-five that's not going to happen.

But gender does matter. A man raping a cis woman has a gender wars element to it, usually something like "Men want sex and women don't, so this man is taking it from this woman, scoring one for Team Men. She's a slut for letting it happen, unless she can prove she's a perfect victim and he's a complete monster, in which case she's a victim of female weakness and needs protected by a strong good man.". Conversely, a man raping a man hinges more on "A man weak enough to let someone rape him is not a real man, but gay-female-feminine. He is ridiculous and pathetic.". There are other gender-dependent examples with female perpetrators, with prison rape, with corrective rape, with rape as a weapon for cultural domination, with isolated communities, and so on.

Of course it doesn't matter in that some rapes count and some don't, and it shouldn't matter at all. Just saying, you should expect different support structures, not identical rape shelters which just happen to be 25% male-populated.
