All good advice, would add, you may not be too bothered if people you know, know what your up to, but your 19, so it's a bit of an ego thing maybe, but remember shit sticks, people talk, and when all your social network knows , because Thay will all tell each other ! And the civvys you fancy get to know, thay may not be as impressed as your mates, society looks down on prostitution and us dirty fuckers who pay for it, this will stick with you for many years, just give it a bit of thought, good luck, wish I'd found this hobby at 19 and not my 50's !
