Cocksleeve/extension

Hi,
Asian chinese married with a 4 inch dick hoping to get some advice for recommended cocksleeve or cockextension.
Recently, had sex w my wife who didnt feel satisfied with a bored look on her face when I fucked her. I asked if she wanted a bigger cock and if it would feel more satisfying.

For the first time, she agreed. Im trying a cocksleeve and hopefully can introduce her to swinging and cuckolding. Problem with the cocksleeve is does it work if I have erectile dysfunction, too. I hv a small cock and I cant get it up.

Some advice from those with experience please.

Experience in what? Small cocks or erectile dysfunction? Or if you're really lucky, both!

Experience in choosing the appropriate cocksleeve for me who has both a small cock and erectile dysfunction.

Your better off getting a hollow strapon
