Cum clumps.. (Slight tmi)

So after I have sex my boyfriend and I notice on his downstairs that my cum has left small clumps of white/cum. It has no odor so im guessing it's just cum? If anyone knows I'm just curious. This has been happening to me since the very first time I've had sex so im gonna assume this is normal for my body but I just wanted to know if anyone else experiences the same thing.
