It all depends on the physiology and dosage of E2. For example, I take 6 mg, my libido has decreased but not critically, which is only a plus for me (I was hyperactive) but now I am sterile and I can have sex without protection, which is more a plus than a minus for me.
My erection is fine, my c*** is still hard. My breasts are a little bigger, but it's not noticeable to others, rather they don't understand the difference.
My growth points are closed, so I have no changes in the hip joint. I also do not gain weight and do not see the distribution of fat by female type. But I see other changes - clean / soft skin, wrinkles have become less-smoothed out, large eyelashes.
In general, the face has become very nice, I would say beautiful. This is not my opinion, so say friends who have not seen me for a long time. This is not an advertisement for HRT, I only describe what is happening to me, I also do not advise taking E2 for teenagers or doing it unconsciously because it will ruin your life.
