Okkkaaayy. So im 18 and feel incredibly pathetic having to ask this but honestly, guys have never been a thing for me since im so incredibly picky so im kinda inexperienced. I have a boyfriend now who i've been with for a long time and ive given him head before and its ok but i want it to be amazing. i have a realllyyyy hard time swallowing and i want to know how to get used to that more but hes ok if i dont so sometimes i dont and finish him with my hand and whatnot yall know the deal. but i want to make it amazing because i love him and i want to drive him crazy and i just dont rly know how since he wld never tell me to do anything special or whatever bc of the way he is. so yaaa.. help? wat do u do that guys like? wat do girls do that you like?
