Problem with choosing sex toys 🙊

Sooooo my fiancé has been some what pushing me to buy a vibrator/dildo. I really think it's part of the fact he has low T and some times he's ungodly tired and can't muster up the energy when I'm feeling myself and want the D lol. I also think it's because on some days he really hates his body and appearance.

I'm cool with toys for myself because he's like GO FOR IT BOOBOO but I've asked him to let me get the "clone a Willy" kit and make one from the mold of his penis and he absolutely refuses. He straight up told me "my dick is small, I don't want you to make one of mine and risk someone seeing a cloned version of my small dick laying around" 😣 broke my heart BRUH. Don't get me wrong, he's not the most WELL ENDOWED man but he makes me cum every fucking time so I don't care! I also think he has a skewed perception on how big the average mans penis is. But anyway. I don't want to get any regular dildo and run the risk of it being much larger than my man and enjoying that more than I enjoy him. He told me that's probably not possible because a dildo is just a dildo. It's not warm or skin like a real penis. But I'm still worried about having toys bigger than him and also how that would make him feel as well.

Does anyone feel like this with their SO?? I'm just concerned about his feelings and if I'm being silly not wanting a dildo bigger than him??
