First, and most dangerous, it leaves you open to getting ostiopesosis. (sorry about the spelling) ever wonder why it's a woman's disease? It can't get started in the presence of testoserone. (check that with a doctor...I know what I'm talking abou0t. Second, it won't reduce the sex drive. Third, it's a pretty good contraceptive, but won't prevent STDs or aids.
As for feeling alone...well, we're all alone if you think about it. But there are some wonderful girls, some of them on this board, who will probably go out with you (if you ask) who might like you enough to think about a long term friendship, and all you have to do is 1. Ask them out...2 be nice to them...(be yourself), and keep it up. Women get lonely too. Maybe the first one you ask out won't like you enough to go out with you a second time....and maybe she will....but ask someone else. I know an NT who has an aspi boy friend, and she sticks like glue to him. And she's not stupid. She just loves him. And from the pictures I've seen of her, she's a knockout physically. Of course, she's smart too. But those women are hard to find. You have to keep looking...and putting yourself out there...and make her like you! Love comes later. You have to be best friends first.
Luck,
