Q: Is semen retention (meaning after going to wife and not releasing semen) permissible? This is a meditative art to control the mind and body. I want to ask you that if I do not release semen or sperm after intercourse for 4 to 8 days? I don't do this for birth control but just for maintaining energy in my body. Is it permissible to do so?

Q: I was looking for a kitaab on sexual relations like what is permissible and what is not but I haven't been able to find clarity on the following:

1) Is your spouse allowed to finger you whilst you're on your haidh

2) Do you only make ghusal after his sexual organ enters your body or do you only make gusal after he ejaculates.

3) If you feel uncomfortable or extreme pain can you stop your husband

4) Is it permissible for a husband to put his mouth onto the sexual organ of his wife

Q: Is it allowed in Islam for husband to rub or put his penis inside wife's breasts?

Q: Does Islam allow one to be intimate with his two wives at once (threesome) in the same room?
