I’m asking for a friend...I’ve noticed as I’ve gotten older (in my mid 50’s), that it can be a bit difficult to cum in certain positions. I’ve found that being on top (or upright) makes it easier to cum. Laying on my back - with a girl riding on top - can be a bit more challenging.
It’s possible that being on top or upright puts me in control. However, I’m not sure if it’s control or if the position. Anyone find certain positions better (for cuming)?
