Ummm... I'm sorry to rain on your parade here, but whether male drow could become clerics of Lolth, changed back and forth over the years. The 2nd edition sourcebook "Demihuman Deities" states that this is possible, though rare (4% of the clergy are male), not all drow settlements will allow it, and males cannot advance beyond 7th level, but in those days practically any nonhuman had a level cap. The 3rd edition book "Faiths and Pantheons" stated that "all clerics are female". I never really played 4th edition, so I don't know what happened there, but I have not seen any restriction on males becoming clerics of Lolth in 5th edition. I could have missed it, of course, but I just went over the books, and have not seen such restriction.
