Basically, i have what is known as delayed ejaculation. I can get it out pretty fast while masturbating which tells me it would be something physical, but i dont masturbate often, if at all. Furthermore, ive got a girlfriend who is actually very good and she turns me on a lot, i have no problem getting it up. But i do pre-cum like a monster and i feel pleasure when i do it. So my problem is, when she does get me worked up, i pre-cum some and then i kinda fall back out of it mentally and it just spirals from there. There was one time she got it out but i had to finish manually for about 30 seconds so idk if that even counts. My situation is something like that. Any suggestions? Hints? Tips?
