I enjoy sex with men very much, I dont "use a male body" (lol). Its just that for me, sex is a very important part of getting to truly know someone, and a way to create positive social bonds. And it makes me and my partner/s happy, so I do it as much as possible.
Theres nothing dirty about it, it's not something to be ashamed of, sex is wonderful and fun most of the time. If you know how to screen for good shags, which I think I mostly do.
Sure you can get a disease from sex, but you can also get diseases from parenting children, or being a nurse, etc. The presence of disease is normal in all human activities. I just used condoms. It's not brain surgery.
I met loads of nice men, shagged a few of them, my MO is just to be as upfront as possible about the things that are most likely to put people off - e.g. I make it known I'm a leftist person, that I dont subscribe to gender role stuff much, dont suffer fools - if the man authentically enjoyed the person I was, and felt safe, and smelled right, then I'd give him a ride. If it was enjoyable, I'd keep doing it. Simples.
I can understand being fearful but I, personally, prefer to take calculated risks in the pursuit of pleasure. The alternative is a kind of death, I think.
I'd rather have many happy friends and lovers vs. lurk in my house mumbling about how no one can be trusted. The latter sounds like a fate worse than death to me.
