Cuck feelings

She deserves better. Even if you had a average sized penis, or even if your penis was big, she would deserve more. If not in size than in variety and frequency. And that's okay. If she's beautiful, you know she is worthy of sexual worship. If you love her and understand all of this, you guys should make a life where she gets what she deserves.

Pick up some electrical devices, some lube, and a bottle of her favorite wine.
Ask her to share with you her deepest fantasies..
In other words - continue to explore each other and keep the 3rd person out of your bed and out of your wife.

Be honest with your wife.
Let her turn you into her sissy girlfriend.

There's nothing wrong with being a cuckold for your wife as long as you are both okay with it. I know that I am not a porn star in the bedroom and that she likes to have a a different guy fuck her. I don't see what the problem is with my wife enjoying other guys it's just for sexual pleasure it's not like she's in love with someone else. I don't need anyone else because she's all that I can handle.

For sure she will be happy to suck and fuck a fat cock

Find her a nice white boy
