Does your vitamin list iodine or selenium?
Do you use iodized salt?
Do not expect to get much iodine in your food, that does not work.
What time of day were your labs done?
TSH should be nearer to 1.0, the lab ranges are not useful.
T4 should be near midrange [11.5] and is low.
T3 should be near midrange[ 2.1] and is low.
E2 is low because T is low.
T is low because LH is low. This is secondary hypogonadism.
Prolactin is OK, you do not have a prolactin secreting pituitary adinoma.
Blows to the head, or whiplash in an auto accident, can damage the pituitary.
We see a pattern of low thyroid function and low-T with many guys in this forum.
Really need the oral body temperatures that I requested to better understand your thyroid function.
Do you get cold easier now?
Are your outer eyebrows sparse?
General hair thinning?
Your T3 could be low from an iodine deficiency. Please provide requested information.
