i agree with you mate, masturbating can get boring after a while. i think the older we get the less we are able to ejaculate, its is true that cumming everyday or frequently means our bodies are using extra energy each time it has to reproduce a fresh batch of sperm.
check out some of Mantak Chia books if you want a better understanding.
for me...
I consider myself a vetran wanker (haha) and when wanking I like to do it hours at a time(when i can) and these days i often bring myself to near climax then hold off from ejaculating. its a really good test to see how long you can hang on. also one trick is to then let your cock relax and shake off your hard on(think about something non sexual...not your dog) once soft insert a finger or some how massage your prostate, prostate dildos are good (check out nexus dildos) as they stimulate the prostate and once you hit the spot (male g spot) this makes me splurt out masses of pre cum and because i am not fully ejaculating i never lose the momentum and can continue for hours. lots of fun. (if you want to take this further..set up a video cam or web cam and record your own movies or broadcast yourself live) as this can add an extra bit of excitment. imagefap is a site that is free - easy to set up and full of fellow wankers getting there bits out on cams.
The other thing you can try once you have been wanking and holding off for hours- do the relaxing thing then try and mentally bring out the pre cum by concentrating deep on your prostate then gently tensing up your body, it can really generate an electrifying feeling within.
I have read lots of books and have since discovered that i have taught myself karma sutra -wanking!! not sure if you are familiar with the ancient method of KS but its basically when 2 people interact deeply at a spiritual and emotion level channeling sexual energies and this creates an internal orgasm unlike any sort of ejaculation type orgasm.
If you want to learn more about your own natural inner energy (Qi) then read up, go online etc and make sure you check out Qigong or chi kung.
if that doesn't interest you have you thought about cross dressing. can be very exciting also!!
