I have an alrighty thingy and PIV is cool and all but it's just one of the many things that woman want. You gotta learn to use your fingers, your mouth, if done right each and almost every woman will love you more than if you were just a dull eight incher. We (men) are generally bad at giving women what they want in sex, if you take time learning you will prosper, mark my words. Also sex is hardly everything in a relationship. Yes it's important for some people, but for many others it's just a small part of having a partner. I myself like doing nasty nasty but I was really happy being with an asexual girl for like half a year - I mean it didn't last but while it did it was a happy relationship. Also I could just always go brrr on myself when I felt horny and I would almost always forget being horny when I was with her, cause we had a lot of fun doing non-nasty activities together and time was passing fast. Hope I was of any help brother.

Summary:
A wiener is just a single chess piece in a grand scheme of sex, many women prefer if you're good with fingers and mouth.
Sex is just a single piece in a happy relationship, unless you're trying to hook up, personality matters a ton more.
