You should not get shocked as long as insulation on the wire is good.
You should not need to caulk weather head if it was properly installed and is not damaged.

Does your service drop have drip loop?
Wires should be looped lower than weather head.

If there is a drip loop you shouldn't have a leak.

As long as head of the weather head is pointed toward top and the service drop has drip loop, water should not get in.
If the joint between conduit and weather head has failed, it is possible for some water to get in. In that case, it may be caulked, but this may be just a temporary solution.

If you don't have drip loop, caulking may stop or slow water entering the conduit for a while, but will eventually fail.
The power company is responsible for the service drop and they should come out and extend or replace the wire to have drip loop.

If you have service entrance cable (a thick gray cable) instead of conduit, check sheeting of the cable. If sheeting has failed, water can get in.
