TBH, girls on the game aren't always a perfect solution either. There are obvious downsides, many in fact, but nothing is perfect in this world and there are a lot of benefits if your need is mainly physical and you don't want any further involvement or hassles.
With P4P it does mainly have the downside of being both (often) very mechanical and routine. Especially if you are going short time with about 1 hour on the clock. I'm also usually quite high when I do it. That helps a lot to relax me more and increase the level of fantasy when it's time to get going. Otherwise, it often feels too stark and sterile if I'm not high and I might overthink the routine aspect of it if I were straight. I did it straight for decades, but now I can't imagine being straight for it anymore. It would seem a bit too mundane.
The short time aspect also adds a bit of pressure. Meaning you've got 1 hour to deliver or time is up. You could spend more time with them, but I really rather not. So I accept the time limit and don't always deliver a payload in time, but that's fine for me too. Sometimes the thrill of a new encounter, a sexy body, and the human touch is more than good enough. I count my blessings. Many men don't even have an option like that available. And something you can't get out of a computer screen and a bottle of slippery goo.
