The random erections and libido died very quickly for me, like literally within the week. Try to avoid masturbating for the first few weeks just in case since that can maintain the function. Both the libido and randoms can come back if you aren't being consistent with your meds, and also if the dosage is too low to get rid of your T.

Regarding aggression, idk. I feel the same as always. If anything I feel more angry lately due to personal circumstances.
