Oh, yes! The clubs. I love the club system and with the right settings, its garanteed to give you a good dating pool to play in :smiley:
I do have a few recommendations, some based on my own experiences and observations as someone who is quite invested in the personal lives of my Sims (the poor things).
You could always go for the classics and nab Lothario. His traits is Active, Romantic (a plus with any guy right? :wink: ) and Noncommittal. Now I don't have any Sims that have had babies with him (yet) but I have seen his offsprings in other threads here and they come out quite nicely. He is also a great friend to quite many of my Sims that are part of my rotational play and a BFF to one of then. Now he does have the nocommittal trait so a marriage or a long term relationship might not be in the cards but who knows. Maybe he will surprise you. But a tip; the best way to nap a noncommited Sim is to move him or her in first (either by household management or just by asking) and then have that Sim initiate the proposal.
The other choice, if you are looking for good genes would be J. Huntington, III. He is also Active, Bro and shares Lothario's Noncommittal trait. My Sim (the very first I played with) actually married J. and they have two little toddler kids atm. Now, J. has the no-commitment trait but after one rejection he did agree to move in. After a day I had him pop the question and they have been happily...well sorta, married for a while now. I haven't seen any commitment tension regarding his wife or kids (he is a fabulous dad, btw) but he has on occasion had the want to change jobs.
If you aren't overly sensitive you could also nap a married or otherwise committed fella. Or maybe just borrow his genes for a while :naughty: I hear that Bob Pancakes is popular for instance and although his traits don't match up with your Sim's at all, he does have good genes, imho.
You have Get Together so there are at least one batchelor household that inhabits two cute male Sims. I don't remember their traits atm but they might be suitable as a prospective mates. I know that according to lore, that one of them is sweet on one of the Fyres girls (another household in that hood) but when I started playing them there was no pink relationship thing with those two so he is probably also available.
Good luck.
