Will I be able to regain function again?

For context I am only a couple weeks back on E and spiro after roughly 5 months of using access. When I did have access to HRT before, I was on E and spiro for about 3 months, and had erectile dysfunction. So, this time around I was prescribed a testosterone topical gel to use down there, but I havent started using it yet out of fear that it'll impact my levels too much. I've been away from home for a while and havent been able to use -it- for almost a week, and have noticeably not been getting hard in the mornings, or throughout the day at all. When I do get alone time, even trying to get it up is a task and it doesnt feel fully hard. This could just be because I'm not actually in the mood, or because I'm experiencing erectile dysfunction again. This makes me paranoid, as I do not want to lose function down there at all. Will using it again regularly after this week bring it back 100%, or am I screwed? If that doesnt work, will the gel help? Or is it gone once you lose it and stay on E?

TLDR: Lost erectile function due to not having a private space to use it for a week, and am concerned that I won't be able to get said function back if I stay on hormones. Any advice would be appreciated !!!
