I think some people will chuckle, others will likely be put off, and some people may miss it altogether. I quite like the idea of having the 'sperm' as your logo, so it's abstract but understandable when you read the tag line.
Personally, I dunno, I'd be wary, some people may assume you've not got a professional approach and likely won't want to associate with you, which will result in loss of freelance business.
On the other hand, if you're going to use such a strong tagline, you've got to have the work and the attitude to back it up. Not cocky, but confident and focussed. The tagline to me says "I push boundaries" and your work has to reflect that.
I think this is perhaps an option for branding AFTER you've got an impressive, unique portfolio. If you already have, by all means, go for it.
