Long time lurker first time poster. Today while the wife was out I decided to try anal for the first time. I grabbed one of her dildos and some water based lube. I threw on a porno and was hard immediately. After I lubed the dildo up and worked it into my ass. It is a small one specifically for anal, but it felt uncomfortable the whole time. I lost my erection almost instantly and experienced a burning sensation in my ass. I was able to work up to an orgasm but my ass was uncomfortable the whole time. Does the sensation go away? I was so uncomfortable I barely fucked myself because it hurt so much. What am I missing? How do I get the most out of these experiences masturbating with some anal action? Thanks in advance for your expertise.
