I have some tips for you
1. Rather then lift a lot, try keeping your muscles under pressure for an extended period of time. For example, don't try and curl 80lbs 4 times, that builds mass. Try and curl 20 lbs for 6 minutes, that builds lean muscle.
2. Run, swim, bike, jog, fight, do something that is cardiovacularly exhausting. Do it often, do it well, do it for extended periods of time. Dont be a ****y. When you think you're done, add 5 minutes. next week add 10.
3. Dont eat ****. Dont eat fast-food. Watch your beer intake (try red wine). Dont eat too many carbs. Dont eat processed bull**** food. Eat whole foods. I shop at Trader Joe's exclusively. I dont know if you have one, but 99% of their product offering is high in protein low in fat.
I will never be the strongest guy at the gym. Probably not even in the top 20%. But I prefer to look good in a bathing suit and have the sexual prowess of a porn star, then impress some dudes in the gym. And yes, being fit, lean and powerful does increase your sexual drive and abilities.
my 2 cents.
