I don't know why but for the last year or so, i can't keep an erection during intercourse. I can keep an erection just fine for manual stimulation and oral sex. The hand and mouth but not the vagina! What's up with me?
Try taking a masturbation break -- it's possible that you're accustomed to a stronger type of pressure and friction that is provided via manual/oral stimulation, but not always via intercourse.
After taking a break from solo-sex sessions using your go-to methods, you can retrain your body and mimic the feeling of the vagina by using a sex toy like the Fleshlight Vulva (http://store.babeland.com/men-sleeves/fleshlight-vulva) during masturbation. But, be sure not to get the vibrating one as that would defeat the purpose.
