Male Baldness Info

So when I was a sophomore in college back in 2003, I got desperate and paid an escort (a.k.a. hooker/prostitute, same darn thing) to have sex because I didn’t want to be a virgin after my teen years. I am now 26/male. I’ve had sex with about 40 women total, more than half were escorts and/or strippers. The remaining majority are girls I meet off the internet on sites like grisliest. I’ve also been addicted to strip clubs and spent thousands, in them over the past 8 years (yeah, I started getting hooked on them when I became legal). I feel like I can’t even pull a girl in public now. I don’t have any confidence, nor do I have any friends. In fact, I have a girlfriend now, and have had a couple others in recent years, but I don’t want to have sex with them. I don’t have the desire for sex with a girlfriend because I’m so use to one-night-stands and no emotion attached, that I am scared to have a girl actually like/love me. I’m not use to that and all I know is wham-bam-thank-you-mam. So girls that I date long term now leave me because I won’t have intercourse with them. But yet, I still find myself online hooking up with girls for wild freaky one-night-stand sex. That seems to be all I know now. Even then, its hard for me to become sexually aroused.
My question is, because of my horrible sexual experiences in my young adult years, have I been ruined? Is there some reason I can’t get sexually aroused any more? I can’t fall in love and have no desire for relationships. My girlfriend of 6 months is about to dump me because I don’t spend enough time with her and don’t have sex with her. Little does she know, I’ve cheated on her 3 times with less-than-attractive older women I met off the internet for one-night-stands. Do I need to see a psychiatrist or something? Somebody help me!!!
Oh yeah, I also take finasteride (the generic Propecia drug) in 1mg doses to prevent baldness. Not sure if that matters tho.

I’m 16 and when I was reading about this I have most of the symptoms
The ones I have are…
increased hair growth on the face, chest, stomach, back, thumbs, or toes—a condition called hirsutism (HER-suh-tiz-um) (i have alot of hair like on my chest inbetween my breasts and no other girls have that, it’s so embarresing :O)
acne, oily skin, or dandruff
weight gain or obesity, usually carrying extra weight around the waist
(i find it hard to lose the weight too)
male-pattern baldness or thinning hair (my hair is kind of thin now but they may be because of layers in my hair)
anxiety or depression (not been diagnosed)
And I usually have trouble sleeping
I don’t want to go to the doctor, I know I should though. Could there be anything else wrong with me?
Also if I did have it, will I ever be able to have kids?
If you want to know more just ask
Thanks
