I'm fond of quickies but don't like having semen dribbling out of me for ages afterwards! I found a good solution, I always wash or wipe myself clean after sex anyway, but I found that gently cleaning out the vagina with clean wet fingers does the trick really well, it also prevents the irritation I can sometimes get if semen stays in me too long (semen is alkaline and can disrupt the natural ph balance of the vagina). The only other solution is to use condoms, leaving the guy all messy instead!
