I've been super fortunate. My first (LTGF) long term girlfriend of 8 years fisted me at least once a day, usually huge toys etc multiple times a day. I would fist her and use toys on her as well, and she got to the point where she would cum the hardest with anal. She also started my belly inflation fetish, watching her blow her belly up with huge enemas till she looked 6-7 months pregnant, then would hold it in as I fisted her or stuffed her with a large toy....You tend to get use to it. I didn't even know it was unusual at the time being young. Along came wife #1, Let's just say that everything I did with LTGF paled to wife 1. Wife #1 I introduced to all the stuff I did with LTGF. She really got into it as well. She was Samantha Luvcoxs. Some of you may remember her... On to Wife #2. She tried to get into my play but was never really into it. We moved to a few new kinks like inflating my balls with saline and N2O. she almost never fisted me, She also never let me do what I consider "normal" sex like cuntlings etc. all very missionary. Had we not had kids I doubt we would have lasted 6 month together. As it is we lasted 12 years. That's what I consider my dry period. Wife #3 is fantastic. She is into anything and everything and we have an extremely healthy sex life. I recently had a Titian penis prosthetic installed due to leaking veins that lead to ED. Now, I have a super hard 8.5 cock when ever I want that last as long as I want! She loves it and calls it her Robo cock lol. All of my partners have fully known about my past activities, as I go into relationships with openness from the start. (no pun intended). Especially after wife #2... My advice, is to be honest with your intended. you might find that they have some of the same kinks you do. Do this early on, while first meeting/dating and get it out in the air so you don't end up with wife#2...
