Thanks wasn't expecting to get such diverse thoughts and made me think a bit.
But maybe to answer some of the questions and thoughts.
I was the one to bring up anal sex with her in the first instance, I enjoy it alot and also on some occasions i wear a penis extender when we have sex to add some length and thickness for her both for vaginal and anal (She brought me that for my birthday). I really love going as deep and as hard as I can go. Hence why I think if I say I give a flat no about her idea that I might be banned from her butt.
I am really conflicted about her using a strap on me. On one hand I feel like it would de-musculate that I become less of a man to her. Of if I let her do it and I couldn't handle it does that make the situation worse in my head that I wasn't even man enjoy just cop it and let her get it over with. I think it would be a-lot easier with someone I would never have to see again
As to her being gentle, based on her comments and the way I like to have sex with her - I have little faith in her being gentle for to long - as she makes joking comments when she brings up the topic I want you to take it like I do, and I could go forever unlike you. (What is an acceptable amount of time for a strap on anyway? - she could just keep going) Its almost feels like she's about to invade a country the way she talks about it. I know she is going to tell her friends with detail if she gets to do it. I kinda feel like I'm that bear that has to hunted.
I have been into a sex store with her once to buy her a vibrator thing, that experience with her and the shop guy made me feel uncomfortable and useless as she overshared with the shop guy and his input and ending up with something that could almost replace me wth more settings then a TV. There is no way I want to go into a store with her to get a dildo and harness thing with the possibility of her oversharing again and another shop person. You just know they will guide her to something that looks impressive etc, while she is explaining where its going to go while Im standing there. Its just a bit messed up he talking to a random person in a shop about what should go up my butt infront of me. Shopping with her is always like she picks for you anyway.
Maybe that was a rant but I kinda feel a bit better for it.
