Is there a sex trick I can do on his dick?

-Im getting kinda bored with my sex life (although the occasional stranger is exciting). I have a boyfriend but he isnt "well endowed" and im just getting disgusted by his Vienna Sausage. I dont want a MONSTER thats gonna rearrange my instestines, but I dont want a Sharpie stabbing me in there either.( Seriously, though, not to be funny or anything I AM DEAD SERIOUS)

I know im not going to keep this relationship going for much longer because I dont want him to get attached. But when I do find a man the right size I want to make sure I give him a night, day, or morning he'll NEVER forget. I want him to drool, curl his toes, and be at a loss for words. Are there any special tricks I could do on a dick? like a flip or spin or special postion or something? Somebody's bound to know the answer, please let me know....

P.S.

dont say head, thats so unoriginal, and Im already a certified master at it... (The certificate is framed in my living room). I want to do something, that I would need to practice for a while to get it just right and blow his mind. Oh and make sure it can be done with a condom on (I may be into random sex, but im all about protection)

THANKS!!!IDK, maybe 69 with him standing up, LOL i saw that on a cup before. :)

Hope i helped1 word. anal
