I really enjoy receiving anal sex.

My boyfriend has found a female girlfriend and dumped me!! We have been very intimate with one another,about three months!! Now,he says,he has a girlfriend!! I'm a bottom,and he tool is just right!! Now,am worried,that my,u know,isn't tight enough,for another lover!! I keep my,u know,really clean,when,I know,gonna' ride the pole!! What should I do??
