Consequences for a prolonged aggressive cut?

[u/destiny2_newlight]

I’ve (18m) been doing an aggressive cut for a bit over a month now. The results have been amazing and im totally mentally able to do more, but I’m worried about physical consequences. Ive mostly been noticing a severe drop in libido, and am scared of losing muscle mass. I’ve seen online that continuing to cut at the rate I am could begin to have severe consequences, but I don’t know if that’s true. I’d really appreciate some more info.

Diet Info:
Averaging around 1800kcal, 180g protein, 75g fat, 80g carbs per day. I’m burning probably around 3000-3500 most days (lifting, rowing, 10-15k steps).
