this is a question for someone I am asking on behalf
what is the Shia ruling on sexual fantasy example can husband and wife discuss sex and talk about their past and what they like and may be talk about others but it will remain with them only .
also in oral sex is licking and sucking allowed.
sorry to ask you these type of questions but it could save some body from GUNAAH
It's not allowed in Islam to discuss about other people sins also it's not allowed to discuss about the sins which you made in the past. Oral sex is allowed but it's makrooh. Specially if your wife don't want it
