and yes, he is right, many females prefer riding on their guy's dick when having sex, as in this type of position they are the ones in control of the movement how fast they like to ride on their guy's penis n they can also decide how deep they want the penis to go inside their pussies to enjoy the pleasure n see-sawing sensation   |
One more observation, girls on top usually can get their big O faster than missionary. Reckon it's the angle of penetration that can be rubbing their g spot. Also, it's less stimulating than doggie that may cause a quicker ejaculation.
The trick to keeping a good FWB is to make sure you ain't selfish, only care about your joy and cumming. Let the lady has hers, ideally several before you have yours. Then you will be too nice to resist.
