Need tips on romantic sex

Sara • 26, trying to take better care of my self and prioritize my health.
Sooo I've only been having sex with a guy for about a month or two~previously a self proclaimed lesbian so I had had sexual experience just not with a guy~and I've found that I can only "cum"~I say that because it's never really a good hard orgasm for me~if the sex is hard and aggressive. But I want to see if maybe there's another way or maybe if I could just get some tips on slower more sensual sex or just achieving orgasm period.
