Marrying a revert

Q: I was married with a husband who had converted to Islam 7 years ago but our marriage lasted for 2 years and we separated due to misunderstandings even though not officially divorced because he doesn't want to. During our marriage he didn't want to pray or fast sometimes even saying he will pray when he is with my family. My question is: Was my marriage valid? Should I ask for a divorce and sit for iddat even if we separated 5 years ago?

Using medications and supplements

Q: I have a question regarding physical relations between husband and wife. My friend is very religious and her husband is moderately religious. She has a question that if her husband uses any medication or pill like ecstasy for good relations then is that allowed in Islam. He is adamant that men use different herbal and all type of medicines for enjoyment and women should also be allowed. Kindly guide us with your knowledge with reference.
