So I was really horny lastnight and a bit drunk.. I bought the Doc Johnson UR3 John Holmes 13" long dildo with a diameter of 2.5" I've had some pretty big toys that I was able to take all the way in my ass... biggest was about 8" insertable and probably 2.25" diameter, almost too big to get my mouth around, and if it were real there's no way I could actually give it head as my teeth constantly hit it. To find a comparison to 2.5" diameter I looked up the dimensions of a soda can and of course the diameter is exactly 2.5". Tried wrapping my mouth around a soda can and no way in hell thats ever going to happen. The size has got me sort of scared... I am a size "queen" I'm always wanting to try bigger and feel more full but practically 2 soda cans stacked on top of each other seems crazy! I do want to get to the point where I can be fisted, double penetrated, but I also don't want to have a gaping ass and fear losing control of my bowels. I know our anal sphincter can stretch quiet a bit, but is there a risk of permanent gaping? Typically I only do anal (only with toys) 3-6 times a year for an hour long session. So far my sphincter seems to go back to normal pretty quickly. Any knowledge is greatly appreciated... I wouldn't mind my ass being a little "looser" than a virgin one, but I don't want it to gape, lose control of my BM's, have gaping flappy sounding farts, or as I'm single and looking to meet a woman dont' want it to be obvious that I like to receive anal. Sure, I'll let her know eventually but I feel that for the most part my pleasure for receiving anal would be a deal breaker at first.. but if we build a relationship and trust she's more likely to stay and trust that she can believe me and that I don't want a man.
Maybe the dildo you bought - 2.5 inches in diameter is only for vaginal use ? The largest diameter anal stretching object I use is about 2 inches. It's not actually a butt plug but a plastic Durex lube container with a rounded tip. It does hurt slightly at first but eases off after a few seconds. Its not shaped like a butt plug - more like a cylinder shape with a rounded end. It slips easily (with lube on it) out unless I sit down on it to prevent it coming out. But I wouldn't want the flat end of it to go in completely as its not the right shape for being able to get back out easily at all. I don't always use lube for anal play unless using the larger anal toy objects or if I want anal insertions made easier.
I'm going through the same thing in my mind. But like you said, once there's trust, most women would discover that they enjoy it probably more than males. There's quite a bit of nerve endings at and around the Cervix, and the stimulation of this region via rectal play can be unforgettably orgasmic for females. Besides, back door play has so many prerequisites and demands that it's best done solo or with someone that you really, REALLY trust, know and love. There is also another aspect to the pleasure of anal, rectal and colonic play/masturbation, and that is the visceral fascial release (many physiologist speculate that this is big cause of the orgasmic experience of being F'd). Visceral fascia is a connective tissue that keeps our innards in place, and fascia is an integral part of any muscular structure. But it has little blood and nutrient supply, so it can get really knotted up over time. And a deep anal session would release tension in areas that are impossible to reach with any type of conventional massage. And this is one reason I'm going for the Cecum (see my post in masturbation if you haven't already). The anal and rectal muscles require quite a bit of warm up due to their uncommon histology. The risk is directly related to how sudden you stretch the muscle (any muscle). If you take your time, and I mean take your sweet, sweet time, breath deeply and relax, you can work your way up to it. But even if you were able to take in, say 10" in girth (about 3.2" diameter) today, and a week later you shove in a 6" in girth up your anus, you may still cause permanent damage. I moved from fingering to the toy you mentioned (at least half of it) in seven months. I took my time and always waited until I recovered from the previous session. Also, people are different. I have VERY strong hip and core (deadlift 3 times my body weight, run sub 6 minute mile), so: A) My body can tolerate things that others' can't, B) I'm always attentive to the slightest feedback I get from my body, and over the years I've become adept at interpreting it. So, again, relax, take you time, and let us know how it goes.
