I live in Harford County, Maryland and driving along back roads I constantly get wiffs of this smell and it bugged me forever. I finally was driving with someone and they commented that it smells like semen and, well, they were right. It is just driving my crazy to try and figure out what the heck this smell is coming from! Only mature answers please, I just want to know if anyone knows if this is a certain plant or tree.

Yes! The jiz trees. that's what i call them anyway and i live in maryland too. It's a tree.

I don't know the answer to this question but I can definitely support you and verify that I too have smelled this plant life before. I live in Western MA and smell it all the time in the summer. Good luck with that answer...let me know if you find out.

Maybe it's a Cumquat!

j/k I have no idea what it could be.

The smell of the blooming acacia trees along the highway in the Santa Cruz mountains was like that. At least, I was told it was the acacias -- I suppose it could have been something else. I don't know if you have acacias where you live ... they have big yellow fluffy blossoms and feathery foliage.

ewwww!!!thats gross y dont u just roll up ur windows?

Bradford Pears, when in bloom, smell like semen here in Rome, Georgia.

I never knew male sperm had a smell to it. I don't know what it smells like either .

I dunno about SMELL, but IMO ,black olives taste like it

Yeah I've smelt it too, a certain kind of tree's pollen smells like the sticky stuff.
