hi I am a male and I am going to be 15 in April.During the last few weeks/months I have been masterbating every 2 or 3 days but I have never actually "cummed". I like girls and everything and get an erection often- at school in front of this girl I have just started going out with and at other random times, this is normal as I've seen posts on here before about it - also sometimes I just want to masterbate so much like once I was in town and went into the toilets twice in about 5 hours to masterbate. I always get a good felling and precome a little bit but if I carry on just nothing happens. I have heard this is normal but nearly everyone can by my age but I cant. Any help would be appriciated. Thanks
