There is one potential problem I see with toys and I'll address it briefly here (and probably get shot down by many but that's ok).
As y'all know - we just started using toys about 3 weeks ago and went from 20 minutes once a week to 45 minutes twice a day. It was great...at first.
We discovered I was multiorgasmic and that was awesome and honestly, I felt better than I had in years.
But then it felt (to me) like it had almost become like a game of "how many orgasms can she have" and "which toys do we try this time in which order".
I started to feel like I was the toy and not like the toys were there to enhance things.
Now to explain it a bit better - you must understand - I'd been having 10 or more orgasms PER session (twice a day usually) to his one every other day or so. (His needs are not as great as mine - it wasn't that I wasn't willing to pay attention to him. He just loved watching me react).
I was exhausted. It almost got to the point that even if I was a bit horny, the thought of seeing a toy made me want to throw it against the wall.
We'd become so focused on our sexual pleasure that the emotional intimacy wasn't there (probably because I was so tired).
So I basically sat down with my honey and said, "We need to talk and please hear me out."
I explained that I was exhausted and that I really needed a short break from "playing". I told him that if he had any needs I really REALLY wanted to help him - but that as for me, I needed some time to build my energy back up. I also explained that I was feeling like I was the toy and that I just needed a bit of time to clear my head - that things had happened so fast that I was confused.
Notice please - I didn't blame him for anything - I put it all on me.
But he understood and said that it was ok and that he would wait for me to approach him again and know that it was time to play some more.
That night we slept in each other's arms and the feelings of desire and intimacy started coming back. It wasn't long before I wanted to "play" again.
You see - I think I'd traded the emotional intimacy of "making love" for just the pleasure of "having sex to have orgasms". I'm not saying there is anything wrong with that - but for us - we need the emotional intimacy too. My husband is a very logical-minded guy who loves trying different formulas to see if he gets the same results and because of that, we needed a break for the personal, emotional desire to come back.
I think that is important for any relationship when toys are involved - that there is enough of a trust factor that either partner can say "no" for a short time and the other partner will give them space.
I hope I've given you something to think about.
