i have been with my boyfriend for a few years. when we first got together he told me he was a much bigger size than he actually is. i didnt think nothing of him never wanting me to touch or hold 'MR HAPPY' even when im sleep. it took months before i realized he was using a toy (in conjunction) with his penis to have sex with me....i was grossed out, i was confused and i was mad as hell! he told me several times he does it to please me bc he knows i like longer thicker penises-and i do. on the other hand he also tells me he wish i could have an orgasm. after such a long time, ive been able to tell him I AM HAVING ORGASMS and I guess the toy gets all my juices and he gets none. im positive he can feel my muscles as they are like a snapping turtle but without the toy there is way less all its worth i simply adore this man and am still with him. ive gotten to where i can accept his solution but honestly my pocketbook can tell the difference and im unhappy about it. he has issues and he expects me to cheat on him he looks for it like you look for your some level i can see myself with him for years but on the other hand i dont want to commit to him bc he has issues that probably are related to his small can fit in the middle of my hand and i feel some attachment to it but i want him to get help to make it this normal for the lady in your lives who adore you too?
2) Irreversible adaptation to sperm competition . It has been suggested that the ancestor of the boreoeutherian mammals was a small mammal that required very large testes (perhaps rather like those of a hamster ) for sperm competition and thus had to place its testes outside the body.  This led to enzymes involved in spermatogenesis, spermatogenic DNA polymerase beta and recombinase activities evolving a unique temperature optimum, slightly less than core body temperature. When the boreoeutherian mammals then diversified into forms that were larger and/or did not require intense sperm competition they still produced enzymes that operated best at cooler temperatures and had to keep their testes outside the body. This position is made less parsimonious by the fact that the kangaroo , a non-boreoeutherian mammal, has external testicles. The ancestors of kangaroos might, separately from boreotherian mammals, have also been subject to heavy sperm competition and thus developed external testes, however, kangaroo external testes are suggestive of a possible adaptive function for external testes in large animals.
