I wouldn't like to say I was pressured into Anal but my partner has an obsession with Anal Sex and when first experiencing Anal I didn't like the feeling and found the experience quite painful, I did carry on trying because it was something he was fascinated by and eventually researched the right advice and started to enjoy Anal Sex. I could of said no at any time and he wouldn't of forced/pressured me into carrying on so even though I was doing it more for his satisfaction I have now experienced how pleasurable Anal Sex can be as well as how intimate and passionate it feels when your enjoying the experience
I was pressured when I was 20. I would actually beg for it now. I think it's an acquired taste maybe. I do need to be properly warmed up. A guy just can't slam it it like a vagina even after 7 years of anal sex.
