What you are describing is not someone with a small penis, but someone who is boring and selfish in both bed and romance. Instead of looking for ways to make you taller (...), you could increase your "sexual intelligence" and communication skills. Every women is different, just like every man is. One of the "secrets for great sex" for example is good communication from both partners, so the other one actually gets to know what is 'meh', 'good', 'great' and "omigod don't stop" on an individual basis. Too many people don't have that skill.
