I am a 19 year old male and have never had sex. I recently got a girlfriend and every-time I talk with her, either over texting or calling, my penis doesn't get big, but releases the pre-cum stuff which is the sticky white jelly stuff. I dont know how to solve this problem because it is so annoying. Is there a drug or some medicine to help or solve this problem? This doesn't happen to me very often, and it doesnt happen when Im talking to girls or anyone, just my girlfriend. We dont talk dirty.
