Hello very frustrated

Hello very frustrated … first let me give you a quick rundown I am a quadriplegic who cannot cum from my accident. I met my wife after my paralysis of course she has a great heart she is very pretty and was a virgin. I’ve got wat they call a sissy penis about 4-5 inches but reality is not that big and I obviously had her virginity. I have approached her with this lifestyle a couple years ago and told her I want her to bring a guy in with a bigger penis she’s likes etc. I want her to feel him deep inside of her. Also she needs to really feel seed being put in her. She’s missing out and I know this. She thinks this is just wrong but it’s not fair to her to never experience this. She goes to church and I’m sure that plays a big role. I’ve cut out all my sexual intercourse try get her to pursue someone else on this level. Nothing affection itself but to get sexual pleasure. She almost went that way a few years back when she was doing her EMT training she started giving a guy a blow job but she stopped out of guilt I was very frustrated because I want her to feel her first organum in her mouuth. Is there any other ideas can try ? I’m struggling here as well as I just don’t care sex cause I can’t get pleasure from it. Thanks!!!
