Yes, it *can* feel good. Depending on the person and technique and patience. It takes longer for a woman to become aroused, so just a "Wham, bam, thank you ma'am" really isn't satisfying no matter who the woman is.
If properly done, both surgically and with follow up dilation depth should not be an issue. Depth for most post surgical woman is anywhere from 4.5 - 6.5 inches. This is very dependent on the person and the surgeon, though.
Additionally, most men are not anywhere near as long as that. And even if they are, modified technique or position can still be satisfying for both.
