ok so i had to think long and hard about this question before opening my mouth but this is what i would do if i were you. I would get comfortable with having actual sex itself first, when i first started doing it i was super aware of my body. i was not comfy at all did not feel special or sexy or nothing. he made me feel wonderful which made me throw my inhabitions to the wind and before i knew it was on my knees my point is that when you feel good you'll do things your never thought you were capable of doing. its only natural that you be shy the first couple of times tho u knw.

for the riding part maybe you should do it on a chair first so you can figure out your rythm, you can use hold on to the back of the chair to help move around, play some music, drinks some drank shit. loosen up, do it spontaneously that'll make it hotter, u dnt even have to get undressed just freaking hop on top of him, put one of ur legs up on something near by that sturdy shit. i think that suckin on some sausage is an acquired taste. i mean i enjoy it and i got friends that dread it. my tips would be, close your eyes, make sure he's like super clean cuz that last thing that you want is a surprise, be creative lick everything, grab his balls, go as deep as you can but don't gag, that throwing up noise ain't sexy oh and you might want to keep soemthing in your mouth like chocolate or caramel, or something not sugary but that tastes good that leaves a lasting taste in your mouth cuz when ur enjoying the taste you kinda forget what your doing and actually suction becaomes better as well as the tongue cuz you start rolling your tongue all around it like naturally cuz of the flavor n shit. but all in all keep ur eyes closed until you get comfortable with looking at pubes in ur face
