How to handjob

Okay ladies... was fingered for the first time today after not letting him because i was too scared😂😂 finally had the courage and damn...he kept going back for more eveytime i was done though like wow he has stamina👅.

However, real question is that he wants to have sex/me to give him a handjob but in reality i just have no experienced with this whatsoever..literally hardly know what a penis looks like.

So my questions:

1. How do you get into a handjob.,,my hands are always in his hair, so no where south. How do you get his d out etc etc take it right back to basics for me😂😂

2. Once you have successfully done step 1, how do i do it good?

3. What do i do with the mess😂!!?

4. How do i know when to stop?

Many thanks!!!
