How can I expedite my ?

I'.m a male of 22 years of age and have been having since I was 14. I've always had issues with reaching climax very quickly. The fastest that I can ever remember having reached s was 5 minutes after not having had for almost a year. The next fastest was 45 minutes. I rarely achieve in under 2 hours, sometimes not even under 3 or 4 even with manual stimulation by both myself and my partner. Or even after an hour or so of oral stimulation I cannot achieve an quickly. I've tried with and without condoms, with and without masturbating before hand. With and without . Often time my current partner, as understanding and as loving as she is, just has a difficult time withstanding all of the stimulation. Even with lubes and different positions and techniques, she eventually becomes sore and I have to "finish" for her. Please, if anyone can refer me to any literature, "dietary supplement" or reference for people like myself, it would be immensely appreciated.
