Welcome to the Forum. I'll be glad to provide our perspective on this. First your LEEP- it's ancient history and does not need to be disclosed to future partners. Your multiple follow-up tests and evaluations provide proof that this is not an active problem and has been dealt with successful.
As for risk, the answer is the same. If he's had multiple other partners there is little chance that he has not already had HPV. Please remember, this is an infection that nearly everyone gets and that few people have complications from. You were one of that latter group and are living proof of how well screening programs work for detecting these rare problems and preventing them from advancing.
The issue of oral HPV is a topic of ongoing research and much of the recent hype, particularly in light of Michael Douglas' recent statements on the matter is speculative concern about what remains a very, very infrequent problem for the millions and millions of people regularly exposed to genital HPV through oral sex. I have pasted several past comments made by Dr. Handsfield on the subject that summarize and repeat our perspective provided in my comments above.

Bottom line however, this is not something to worry (or loose sleep) about. EWH
