I find it pleasant as well to have some fun talking during foreplay.
Just like a day on a beach, you dive into pleasure again and again.
That's how a lot of very pleasant sessions go. Sometimes people book over an hour because they want to chat over a glass of wine in the living room for a bit before heading to the bedroom. A lot of guys can't go for more than one shot or need a lot of recovery time before the 2nd round.
Some others just want to shower and head to the bedroom almost right away and that's fine, too! I just think it's important to tell the provider what you want. If a provider thinks it's rude if you ask how many shots and you absolutely want a certain number of shots, she may not be the right person for you.
An issue I've had with clients who want multiple shots is that their eyes are bigger than their stomach so to speak, they think they'll be able to go for a certain number of shots but they have to really force themselves and it just feels like they are working lol.. that's just my opinion but the session has to be pleasant for both people... not a shot contest. But you know your own body. If you know you can cum multiple times within 90 minutes or 2 hours have fun!
