As a serious romance fanatic. I recommend Jennifer Crusie/Bob Mayer if you like funny romantic books. I just finished these and as a woman found Don't Look Down seriously lacking in the mushy stuff.
Bob Mayer is a great action writer but sucks when it comes to romance. The second book Agnes and the Hitman was definitely much better and I laughed the whole way through it.
I don't think of Stephanie Plum series by Janet Evanovich as a romance but they are great books if you like funny cozy mysteries. Yes there is a love triangle but they have a little bit of everything. I am huge fan of this series!
However they are written from first person who is a female but I know alot of men read the series so I am throwing it in there.
Suzanne Brockmann's Troubleshooter series is about Navy Seals finding love and has been recommended in similar threads for guys to try.
Catherine Coulter's FBI series is pretty good. It has romance in it but it's more a mystery\thriller type.
I just bought a book written by a guy who is writing a series with his wife. Nico Rosso is his name and his wife is Zoe Archer. It's a steampunk series.
I'm always interesting in guys writing romance. Not many out there but there are times I prefer a real male perspective and I found Mayer's quite macho monotone dialogue entertaining.
