Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
1) Tattoos whether temporary or permanant, are not permissible in islam.
Abdullah ibn Masood (Radhiallahu Ta'ala Anhu) says that:
I heard Rasulullah (Sallallahu Alaihi Wassalam) say:
"Allah has cursed the woman who does tattoos and the one who has them done, the woman who plucks eyebrows and the one who has it done, and the one who files her teeth for the purpose of beauty, altering the creation of Allah."
(Narrated by al-Bukhaari, Muslim Vol 2)
2) Natural breast or male sexual organ enhancement will only be permissible if this is done in a permissible way (i.e.) the treatment is administered by a male physician (for men only) and female physician (for women only) and there is no haraam ingredients nor there is nothing else impermissible and this procedure does not cause any harm then it will be permissible.
