I (20m) have done it with 3 people, two of them had a smaller build than I do. Kaya naintindihan ko naman when they rejected nung tinanong ko if we can try anal. But yung sa pangatlong girl(21f) naman I met noon on a dating app, we were trying to turn each other on through dms the night before and she asked if I wanted to try anal. Syempre sinabi ko yes, and proceeded to talk about my size. I'd say mine is just average compared to the ones I see on the internet, and I sent her a photo of it pa. So the next day I went to her place and nag foreplay muna and when she saw it she began to hesitate doing anal na. Syempre medyo nalungkot ako pero we just proceeded to doing the deed nalang. Yeah naintindihan ko naman na anal isn't for everyone kaya no hard feelings sa girl and matagal nanaman yun, I'm just frustrated na I still didn't get to try it HAHAHAHA
