well...i got into bdsm before i was 18..so i had 2 hide things very well and couldnt buy actual sex toys....
something already mntioned...clothes pins..and if you're into pain..you can modify then some....there were pics i believeinpersonal photography...it just makes things a lil more fun
i also used electrical tape for breast bondage...
a strange thing i guess ws using markers to kinda stretch myself down there...My old called it preparing me for him....
twist ties work aroundsome nipples too...not for mine (nipples r too big) but my friend does it...
i think thats all..
