I'm not exactly sure. I know that 5-ht1a agonists have a facilitatory effect on certain aspects of sexual function.
5-ht2c antagonism supposedly reverses the negative effects of serotonin reuptake inhibition on sexual function. On the other hand, I think acute 5-ht2c agonism can facilitate certain aspects of sexual function (erection etc.)
Not sure about 5-ht2a. I know 5-ht2a agonism release oxytocin, so this might facilitate certain aspects of sexual function.
I think I remember reading that 5-ht2c antagonism and 5-ht2a agonism had synergistic effects on sexual function in some rodent model of sexual dysfunction.
OTOH, I think 5-ht2c agonism is what is responsible for the anti-premature ejaculation effects of SSRI's.
So, perhaps if ejaculation is premature, 5-ht2c agonism is beneficial, but if it is latent (or impossible) some degree of 5-ht2c antagonism is beneficial.
