Mean Girlfriend

M
My girlfriend and I have been trying to get regnant for a while. I was at the doctor for a regular check up a couple weeks ago, and he suggested I abstain for 5 days before the middle of her ovulation. Anyway, last night, we tried it. Just as I was about to ejaculate, my penis started to go soft. It does that sometimes. Because i was losing the erection, my girlfriend reached behind and pulled my penis out of her, forcing me to ejaculate onto the bed and waste my semen. It took a lot for me to abstain for 5 days...I don't know about the guys here, but after 2 to 3 days, I ache...so, after 5 days, /I was aching. She is mean. This ruined this month's attempt for me to impregnate her.
