The anal sphincter of a person who has an assgasm usually contracts rhythmically, just like a woman’s vaginal walls contract when she orgasms and muscles at the base of a man’s penis contract when he orgasms. It feels similar to a traditional orgasm but deeper, with sensations that can radiate beyond the ass and down to the inner thighs.
There is no single way to achieve an assgasm, although some people find certain techniques help them have an assgasm more reliably than others. Experimenting with all these techniques can help you find what works best for you.
An assgasm often occurs during anal penetration. Penetration isn’t necessary for some people. Simply fingering around the anus can be a great way for novices to test the waters and perhaps experience an assgasm. Digital penetration with one or more fingers can also be effective. It’s best to go slow, trying just one finger at first before increasing the intensity with more fingers. Keep fingernails trimmed and smoothly filed to prevent anal tearing. Using a good lube or putting fingers inside a medical glove or condom will make any kind of anal penetration easier and more pleasurable.
Analingus, or licking the anus, can also be an effective path to assgasm. The giver should use a dental dam to protect themselves from harmful bacteria. It’s also a good idea to shower, have an anal douche or enema, or at least wipe the ass with a wet wipe before analingus.
Playing with a butt plug or anal vibrator can also bring on an assgasm. Look for toys designed to stimulate the prostate. A lubricant can also make insertion easier, but make sure your lube is compatible with your toy’s material. A water-based lube is always a good option. Do not share toys or use them in the ass and vagina unless you clean them thoroughly.
Of course, an assgasm can also occur during anal sex. Positions which provide deep stimulation, especially of the prostate, can be the most effective.
