A good relaxing exercise ,
_ massage your anus with lube , and insert from time to time a finger , not too deep 1 - 2 inches
_ stay going on to massage but play with your anus and enough lube , now try with your thumb
_ going on now use two fingers
there are medium plugs or candles for after , and never forget ,
Don't let him shove his penis in your anus,
take his member and lead it in your anus,
clench it strong then push like to poo, and control the depth
easy to say hard to do if you masterbating it will be very helpfull
Success to you, and pleasure too,
Using a vibrator like the Hitachi Magic Wand on your privates will lead you to orgasm,
turn your back to him, use your vibrator, and lead him,
in some days you will write here it was O M G
