sexual shortcomings 

A fancy polite way of saying that a man has a tiny little dick and will never be able to satisfy a woman if for no other reason than that he can’t get very far inside her.

Brenda: Why happened with you and Tom?
Charlotte: Tom has some…well…sexual shortcomings.
Brenda: let me fix that for you.
**Brenda and Charlotte make out and have hot lesbian sex**

shortcummings 

(1) Flaws or inadequacies regarding ejaculation.
(2) Faults related to not depositing your jizz inside a woman's love-tunnel in a properly-timed or correctly-positioned manner, such as shooting your load before you get your cock all da way inside of her vagina, or being so eager and horny dat you spurt before you've even attained a full erection, and so your sperm comes out of only a "stubby" dick and thus does not reach fully to da back of her coochie da way she wants it.

Da term "shortcummings" could also refer to however many "secondary" ejaculations dat you manage to serve da lady wif subsequent to your having cum da first time; usually these "additional" outflows will be quite weak and minuscule compared to your initial release, and so they will definitely "fall short" of both parties' desires or expectations.
