Failed at using dildos. I need help and dont know what to do.

A little back story about me....I brought up this lifestyle (stag/vixen) 3 years ago and my wife has said no. Im 51, she is 44. We have been together 20 years. I love my wife so much and we have a great marriage. She says she likes how my 5.5" dick feels and she can come when she's on top of me. She also says that she can have sex as just sex but bringing another guy into our sex life is playing with fire. I'm bored with vanilla sex no matter how great.

I recently got her willing to try some bigger dildos when we have sex. So last night we tried a realistic (Realdick) dildo that was 7.8" by 1.7". I made sure to use lots of foreplay, made her cum with my mouth, warm the dildo up, use lots lube and go slow. She said the dildo didn't feel good and hurt a little. At no point did she seem to enjoy it. I gave up so she climbed on top of me and came in a minute or two with me inside.

What did I do wrong? Is it my technique? Should I use a 8.7 x 2" wide dildo so she feels more full? Maybe some women just prefer real dick and dildos.

I so want to give her an orgasm by stimulating the inside of her pussy. She says her orgasms are great and doesn't need anything else. I've also explained that watching her get off by another guy is different than when it's just me doing it.

Should I tell her about this site? I think she would just get pissed off as she has already said no. I just want our sex life to be even better. So many people have said the LS is amazing and they wish they started sooner.

I don't know what you do. I'd like to hear from the wives out their and see what they think.
 
Look into the Lovense toys. My wife started with a Lush and quickly began adding to her collection. One by one she added Nora (by far her favorite), Ferri, Osci, and her most recent purchase about a year ago was Gemini (vibrating nipple clamps).

Best part of the Lovense toys is that they are also Bluetooth controlled so they can be controlled by anyone, anywhere in the world. Needless to say some of our friends have had some fun with my wife over the years and have greatly expanded her way of thinking when it comes to being a naughty wife.

Good luck!
