Sure, you may encounter partners who may be turned off by that, as with any physical or sexual preference. But you’ll also find partners who are turned on by it, or who don’t care either way. It’s all about finding the right sexual compatibility with the right partner — and that might include adding more oral stimulation, manual stimulation, sex toys, and so on. It's 100% entirely possible to have an amazing sex life with any size penis (or, you know, none at all).
One of the things I took away from dating him is how insecure men can be about their penis size. So whenever I date anyone, I always tell them the very specific details in how I love their penis. I never lie – that would be too tough to maintain long-term – but I always find something. Huge girth. Love the way it curves. The hardest I’ve ever been with. I can barely fit it in my mouth. Whatever. I don’t understand the penis-insecurity but I am going to do my best to rid this world of penis insecurities, one cock at a time.
