Can I Contract STD By Touching Penis Of A Male?

Hi, my name is Kristie. Can you get any kind of std or hpv from a handjob? I just gave my new boyfriend one, and I know he s had multiple partners in the past, while I m a virgin, but he kept ensuring me that he s never seen any sign of having a disease. I didn t see any warts or bumps on his cock, but didn t get a close look. I also only touched it with my hand, with some occasional spitting on it, but never made mouth contact. He did ejaculate while I was jerking him though and that got on my hand a bit. I m very paranoid about germs due to my OCD and germaphobia, so naturally diseases terrify me, and I ve been avoiding touching my mouth, lips, any part of my face in general, along with washing my hands every hour in hot, soapy water.
