I need advice…

For some background; I am just a week and half short of 2 years on T and I feel like my growth has been minimal, my wife says it has grown a lot but it’s just hard to tell because I have a lot of fat deposited all around in that area so if I push down around it then I have a decent amount of growth according to my wife compared to how much I had pre T… I still feel some way about this and had bought a pump device from a sex shop… no it didn’t have a gauge on it, anyways I had used it daily for like 3 weeks for 20mins at a time… well the last time I used it I went to my normal 3 full pumps and it didn’t feel tight or anything so I pumped it one more time and left it… so time goes by and I finish my sets and I pull it off and there is blood in the tube, I freak out take pictures and I see I gave myself a blood blister on the foreskin area… I popped it and didn’t think much of it… it never really like hurt or anything but about a week later my wife and I were getting ready for spicy time and she went down on my to suck me off and she said that it would get hard then go soft… could I have done something to really damage it? It’s been about 2 weeks now and she said it still does it and that it doesn’t feel as hard in her mouth anymore… I hope I didn’t do anything bad to it as I am about to start peeping for Phallo next year…
