I hope I am not out of line in suggesting she could return the favor to get you ready, so to speak.
This probably sound slightly selfish, and maybe it is - although I guess fairly common practice - mostly I've given oral only when not in the mood for orgasm myself, e.g. when hungover (which has happened far too often!). Having the favour returned has happened, however, albeit infrequently - I hadn't thought about it but now you mention it those times may have been when my partner actually wanted cock instead of/or after oral. (Off-thread, but I think this is yet another example of having to be psychic in order to know what others actually want/need!). As a result of this thread I wonder if t-shirt slogans like "tell him you want oral" will come out?
