This thread is an absolute car-crash full of men who give off BIG virgin energy.
Women are (wait for it, this may blow your minds a little) all individual people who have different preferences and can't be generalised into "women normally prefer bigger dicks" or "women will cheat on you have a small dick" or "women prefer money to big dicks".
At the end of the day, whatever dick you have, you can't change it. Communication is the key to good sex.
Actually ASK your partner what they like and what they don't like. Learn more about how to turn them on, and what feels good to them. Maybe consider using your your mouth, or hands, or a toy or two. Basically, remember that activities in the bedroom aren't all about your cock, and that - God forbid - it might be a little about whether your partner is getting pleasure out of it too, and, if you're not sure, ask.
In summary, if you think penis size is the only thing that makes a difference to a woman's enjoyment levels when having sex with you, you're probably terrible to have sex with.
Now rather than talking online about what women like, why don't you go find out?
