no need to challenge yourselves. as long as both parties enjoy the vibe then orgasm is just a bonus. It doesn't mean that the girls don't like the times with you nor underrate your skills. Skill is one thing, but also feelings is important as well. I know one legend who can make me cum almost every time ( probably one time we missed it because I was too tired) but I don't have desire to make love with him. Sorry A&L but believe me, you still receive my compliment all the times.
