I have a problem and I am not sure if it is premature ejaculation!, OK, I am in my first sexual relationship now and I have being going out with my girlfriend for 6 months. I am having problems in "keeping it up" sometimes, but only sometimes, but there's one thing I want to find out. Right, when me and my girlfriend are doing stuff I get very sexually excited and the top of my penis when she starts playing with it goes wet, as in some liquid somes out and after that it is hard to get the good feeling again if you know what I mean, I have been reading stuff about premature ejaculation but none really match to what problem I am having. So can someone tell me? I get sexually excited and then a see-through liquid comes out of the top of my penis and the feeling isn't the same anymore. Can someone tell me what this is and what it is caused by please? and if someone can tell me what it is, is there anyway of stopping this so I can keep the good feeling??
