I do 2000 a day. I'm in the car a lot to and from work. I do them so much sometimes I'm not even conscious of doing them.
The end result for me is erections that are so hard they hurt (that good hurt you know?) and I can split my orgasms. I split my load into several spurts, which is hot for the lady if I'm pumping her. I tell her I'm goign to spurt and I let go a nice big gooey rope hard and fast right inside her cunt. I do this like 8 times till I'm just having dry contractions, then I let it go and have a mind fuckign bending orgasm, usually dry, but sometimes a little more comes out.
So yes, do ya fucking kegels, and no, your not doing nearly enough. I started with a high number. I do quick flexes. Start off with 1000 a day, 500 a pop. YOur dick will thank you. Add some L-argenine in with that, 500mg 3x a day and 3 500mg hour before sex with no food and you'll be rammin that lil slut with a fucking 2x4 stickin off your pelvis
No. You can do them completely flaccid. Flexing you PC muscle while erect will strengthen the muscle even more, and putting a towel on top of that will strengthen your PC muscles even MORE.
