This is definitely for the experienced anal player! As a person who is experienced in anal play, I highly recommend stretching yourself out with smaller anal toys before using this monster! A good rule of thumb is if you can insert the doc johnson large butt plug up your ass and leave it there for 30 or 40 minutes, then you should be sufficiently ready to take in Rambone. I\'ve read reviews where others talk about getting the whole thing up their ass and find that hard to believe! More recently, my Mistress had just gotten through fisting me and I was only able to take about 8 to 9 inches of Rambone attatched to a strap on. But, I do recommend using vaseline with this product as it provides the best lubrication. Oils, are not as effective and water based breaks down to quickly! Let Rambone\'s head pop in but then the thickest part of the shaft begins. At it\'s thickest point, it is 7.75 to 7.875 circumference. You\'ll feel as though you have a baseball bat up your anal cavity, but oh is it ever so fulfilling! Only reason I give this one 4 stars, actually I would give it 4.5 is because it is difficult to mount the suction cup on a flat surface and ride it! The dong stands to tall to sit on it! I recommend suctioning it to a wall and backing up on to it doggie style . You can control the depth of the penetration and speed better that way! If using a strap on, I recommend the Terra Firma Leather as it is strong enough to hold the weight of this mammoth dong and keep it in place for intense anal play! Definitely a must have for experienced anal or vaginal players!
