I have found that since i started takinng the well known "Wellman Original" tablets that you can buy anywhere my sex drive has increased dramatically and i feel less tired, have more energy generally, also this is supported by regular exercise and a reasonably healthy diet.
this tends to give me the urge for more sex. for the shorter recovery time and prolonged duration i take Golden root herbal tablets which you can get online or from Sainsburys or from the vending machines in some toilets. Take one 45 mins to 1 hr before a punt and it will give increased stamina and reduced recovery time, it does desensitize you a bit and going for the second pop in an hour booking can be difficult but i enjoy the ability to get hard and have a great sustained fuck just as much as the end result, i do experience some side effects such as indigestion which you should use Ranitdine tablets available from chemists or supermarkets which does the trick. You will also feel flushed and sometimes a mild headache or stuffiness but a couple of ibuprofen work for this, (I saw this in a post somewhere so gave it a try and it works)
I know it sounds like a cocktail of drugs but the effects will last all night and into the next day, if you take the indigestion and headache pills then you wont feel rough later or the next day either which can be the case if you don't.
It works for me, you perform better fel bigger have a very intense orgasm and you can get it up again easily.
I used to only go for 1/2hr bookings because i would come once then wouldnt be able to get up again for about 45 mins or so despite all efforts.it was not good for my self esteem and knocked me quite badly.
Now i can enjoy longer sessions and my record now is 5 pops in 3 hrs at a TLC party, which has not happened since i was in my 20's
I suggest you spend 3 quid at Sainsbury's and give it a try plus the indigestion and Ibuprofen.
the only trouble is i feel horny a lot more now and its costing me a fortune in punts !!!
