the following reasons:

1. I french kissed a guy who visits prostitutes and also kissed a lot of girls in clubs. He also touched himself a little and fingered me...but we don't have any skin to skin contact.

2. The guy I am currently dating used to be a player. I gave him a blowjob with no condom on, kissed him when there is a huge cut in my mouth, and also let him rubbed his penis on me (tip entered a little with no condom). According to him, he is clean. But I do not know because he is a player who used to sleep with a lot of girls. 

3. I kissed two random guys in the club before.

Any possible way I can get any types of sex diseases without intercourse and the reasons mentioned? I never had sex before.
