The way I see it, condoms and pulling out can often be a selfish act on the man's behalf. I know that sounds crazy and would probably draw a lot of scoffs from people....but it's true to an extent.
It's OK to for a man to be selfish sometimes. I have no reservations whatsoever from occasionally walking in to a plate's house when picking her up for a date, throwing her down and having my way with her.... entirely for my own pleasure with no intent to keep going when I am done. I've had plates admit they really like
You cannot keep going with a condom on after orgasm. It will come off. You have to stop, take it off, clean up, put another on, etc. Pulling out is no different and requires cleaning too if you're going back in (there is still sperm there). Both kill the momentum and take a woman out of her "zone" (and yours). Once a man is satisfied and the mood has cooled with the interruption, it can often be a lot of work to get a woman back to that zone and keep going all the way to orgasm from scratch again
