As the type that likes to play for an hour or more I find that foreplay can be very important. I don't just mean getting my dick sucked or a lady getting her vagina licked and fingered. I mean taking the time to kiss. The build up from lite pecks to nearly intercourse via two mouths. Also taking the time to explore the others body: breast, neck, legs, ass, back, and of you're the type hands and feet.
Not to say getting an extended or lengthy blowjob is terrible. I just personally find my time overall is better when the foreplay is all encompassing.
I know this is just me but also I am far more likely to be able to go multiple rounds with proper buildup from foreplay. I've had an adventure or two were the provider just falls to her knees and blows. No kissing. How you doing? I get my nut. I just don't feel the need to go again, or visit again in the future in those cases. Don't be scripted, mechanical, or log from 0 to 150mph in 0.1sec. It can be a turn off. There are many of us that like the build up.
