Lydia is a bit— sexually aggressive.
If you keep leaving him sexually frustrated, he's likely to start looking for a substitute.
Was he sexually frustrated, and did he think about other women?
Although some attain their full development in the body of a single host - in this respect differing from all other Entozoa - the majority do not become sexually mature until after their transference from an "intermediate" to a "definitive" host.
After a longer or shorter period it enters the alimentary canal of its proper host with drinking-water, or it bores through the skin and reaches the bloodvessels, and is so conveyed through the body, in which it becomes sexually mature.
(In Hydra, on the other hand, the individual is usually hermaphrodite.) The medusa always reproduces itself sexually, and in some cases non-sexually also.
- Simple polyps which become sexually mature and which also reproduce non-sexually, but without any medusoid stage in the life-cycle.
In this it remains until the completion of the transformation into the sexually mature insect, which then emerges from the case, leaving the pupal integument behind.
Sexually mature whilst still in the larval stage.
They reproduce sexually, and with doubtful exceptions are of separate sexes.
This anomalous phenomenon is still obscure, for we do not yet know whether the second embryo is developed sexually or asexually from the first.
Through this temporary protection the active pupa, which closely resembles the mature insect, subsequently bites a way by means of its strong mandibles, and rising to the surface of the water casts the pupal integument and becomes sexually adult.
The gastrula has now become an actinula, which may be termed the distinctive larva of the Cnidaria, and doubtless represents in a transitory manner the common ancestor of the group. In no case known, however, does the actinula become the adult, sexually mature individual, but always undergoes further modifications, whereby it develops into either a polyp or a medusa.
The reproduction of the higher plants takes place either asexually by the formation of buds or organs answering thereto, or sexually by the production of an embryo plant within the seed.
The Peronosporaceae reproduce themselves sexually by means of antheridia and oogonia as described in Pythium.
Everything that is sexually begotten is impure.
This is in consonance with the facts already mentioned that zoospores germinate forthwith, and that the sexually-produced cell or zygote enters upon a period of rest.
The evidence that the correlation between sexually produced brethren is the same as that existing between the asexually repeated organs on an individual body renders it impossible to accept Weismann's view that one of the results produced by the differentiation of animals and plants into two sexes is an increase in the variability of their offspring.
When fullsized they leave the water and spend a quiescent pupal stage on the land before metamorphosis into the sexually mature insect.
When once sexually ripe the axolotl are apparently incapable of changing, but their ancestral course of evolution is still latent in them, and will, if favoured by circumstances, reappear in following generations.
It is an almost universal attribute of polyps to possess the power of reproducing themselves non-sexually by the method of budding.
Such forms he distinguished as Coelentera, and showed that they had no special affinity with echinoderms, polyzoa, &c. He divided the Coelentera into a group Hydrozoa, in which the sexually produced embryos were usually set free from the surface of the body, and a group Actinozoa, in which the embryos are detached from the interior of the body and escape generally by the oral aperture.
Sarasin (17), whose great work on the development of Ichthyophis is one of the most important recent contributions to our knowledge of the batrachians, Amphiuma is a sort of neotenic Caecilian, a larval form become sexually mature while retaining the branchial respiration.
I'm just sexually frustrated.
