My boyfriend seems to wayy too soon. It's nice when ever we are in a real hurry but on days where we have the whole day to ourselves it's an absolute curse. His usual span for regular ejaculation is about 10-15 min at least 20min at max. Not to sound selfish but he's done quite a bit sooner than I and it really takes away from the sexual experience for me. Any suggestions.

If you have going to have some quality alone time ask him to masterbate a couple hours in advance. This will give him some better stamina for intercourse later. Also have him spend extra time on foreplay exclusively about you, while that will arouse him without the direct stimulation of anything he may be able to wait long enough for you to finish first.

Work with him on delaying his orgasm, often men can delay their orgasm by stopping all stimulation by not moving this allows them to build some control for when they will ejaculate.

Here's a good tip. Are there any positions that really work for you but don't give him nearly as much stimulation? If so, front-load the sex with these and it'll increase the chances of you peaking before him.

Then again, I've never had a problem peaking before the girl.
