My initial reaction is that you do not know enough, therefore you are not committed enough and you do not deserve to join and take the space of someone that is.
However I will engage my more helpful side along with the other 'tossers' who have aired their concerns and doubts.
If you are worried about being sick or when you can voluntary retire (volret or leave), you shouldnt join
If you are worried about being away from your wife, you should a)not join or b) join the RAF
If you do not know whether the RN has fast jets or not. Actually Im not sure how to politely answer that one.
If you dont realise that you will have 2 marriages and that your 1st one will be the least well served. If you cannot take the banter, the criticism etc. If you have not done your homework to the extent that you are sure in your knowledge that this is the hardest possible thing you are ever likely to do requiring 100% commitment. If these questions along with 'can i kill or be killed' and am i happy with what happens on tour, stays on tour and many more are not top of your agenda, you need to start from the beginning.
If I were still serving I would have the name of your 'liaison officer' however. Get yourself down to Culdrose, by appointment. Spend some time in the wardroom, talk to the guys and girls, see the atmosphere, fun, trepidation, intensity, professionalism, commitment and the officers and the 'gentlemen'
I am inclined to believe your questions are genuine, your commitment I am not!
